Cav-a-Jack

The Cav-a-Jack is a mixed breed dog–a cross between the Cavalier King Charles Spaniel and Jack Russell Terrier dog breeds. Energetic, friendly, and playful, these pups inherited some of the best qualities from both of their parents.
You can find these mixed breed dogs in shelters and breed specific rescues, so remember to always adopt! Don’t shop if you’re looking to add a Cav-a-Jack to your home!
The Cav-a-Jack is a great dog for a first time owner to consider. These pups are playful and sociable; they love to spend time around people and will make great playmates for any young children in your household. They also have something of a mischievous side! Due to the mixed breed’s smaller size, they’re adaptable to apartment living, just as long as you make sure you meet their exercise requirements. Cav-a-Jacks are known to be smart and inquisitive dogs who will benefit from interactive toys in their environment.

Breed Characteristics:
Adaptability
Adapts Well To Apartment Living
4
Contrary to popular belief, small size doesn't necessarily an apartment dog make. Plenty of small dogs are too high-energy and yappy for life in a high-rise. Being quiet, low energy, fairly calm indoors, and polite with the other residents are all good qualities in an apartment dog. And you can find an awesome crate for your dog here to give them a little more personal space in your apartment.
Good For Novice Owners
4
Some dogs are simply easier than others; they take to training better and are fairly easygoing. They're also resilient enough to bounce back from your mistakes or inconsistencies.
Dogs who are highly sensitive, independent thinking, or assertive may be harder for a first-time dog parent to manage. You'll get your best match if you take your dog-owning experience into account as you choose your new pooch.

You may also want to consider adopting a senior dog, as they tend to be less demanding of your time and energy. You can keep your senior dog active well into old age by providing them with joint supplements to fight the symptoms of arthritis. Adding Glyde Mobility Chews to their routine can help their joints stay healthy.
Sensitivity Level
3
Some dogs will let a stern reprimand roll off their backs, while others take even a dirty look to heart. Low-sensitivity dogs, also called "easygoing," "tolerant," "resilient," and even "thick-skinned," can better handle a noisy, chaotic household, a louder or more assertive owner, and an inconsistent or variable routine. Do you have young kids, throw lots of dinner parties, play in a garage band, or lead a hectic life? Go with a low-sensitivity dog.
Tolerates Being Alone
1
Some breeds bond very closely with their family and are more prone to worry or even panic when left alone by their owner. An anxious dog can be very destructive--barking, whining, chewing, and otherwise causing mayhem. These breeds do best when a family member is home during the day or if you can take the dog to work.
Tolerates Cold Weather
3
Breeds with very short coats and little or no undercoat or body fat, such as Greyhounds, are vulnerable to the cold. Dogs with a low cold tolerance need to live inside in cool climates and should have a jacket or sweater for chilly walks. You can find a great jacket for your dog here!

Tolerates Hot Weather
3
Dogs with thick, double coats are more vulnerable to overheating. So are breeds with short noses, like Bulldogs or Pugs, since they can't pant as well to cool themselves off. If you want a heat-sensitive breed, your dog will need to stay indoors with you on warm or humid days, and you'll need to be extra cautious about exercising your dog in the heat.
All Around Friendliness
Affectionate With Family
4
Some breeds are independent and aloof, even if they've been raised by the same person since puppyhood; others bond closely to one person and are indifferent to everyone else; and some shower the whole family with affection. Breed isn't the only factor that goes into affection levels; dogs who were raised inside a home with people around feel more comfortable with humans and bond more easily.
Treats can help the bonding process go more smoothly. Try giving your dog Glyde Mobility Chews to help them see you as a provider and to keep their joints healthy!
Kid-Friendly
4
Being gentle with children, sturdy enough to handle the heavy-handed pets and hugs they can dish out, and having a blasé attitude toward running, screaming children are all traits that make a kid-friendly dog. You may be surprised by who's on that list: Fierce-looking Boxers are considered good with children, as are American Staffordshire Terriers (which are considered Pit Bulls). Small, delicate, and potentially snappy dogs such as Chihuahuas aren't always so family-friendly.
**All dogs are individuals. Our ratings are generalizations, and they're not a guarantee of how any breed or individual dog will behave. Dogs from any breed can be good with children based on their past experiences, training on how to get along with kids, and personality. No matter what the breed or breed type, all dogs have strong jaws, sharp pointy teeth, and may bite in stressful circumstances. Young children and dogs of any breed should always be supervised by an adult and never left alone together, period.
Dog Friendly
4
Friendliness toward dogs and friendliness toward humans are two completely different things. Some dogs may attack or try to dominate other dogs, even if they're love-bugs with people; others would rather play than fight; and some will turn tail and run. Breed isn't the only factor. Dogs who lived with their littermates and mother until at least six to eight weeks of age and who spent lots of time playing with other dogs during puppyhood, are more likely to have good canine social skills.
Friendly Toward Strangers
4
Stranger-friendly dogs will greet guests with wagging tails and nuzzles; others are shy, indifferent, or even aggressive. However, no matter what the breed, a dog who was socialized and exposed to lots of different types, ages, sizes, and shapes of people as a puppy will respond better to strangers as an adult. Remember that even friendly dogs should stay on a good, strong leash like this one in public!

Health And Grooming Needs
Amount Of Shedding
2
If you're going to share your home with a dog, you'll need to deal with some level of dog hair on your clothes and in your house. However, shedding does vary greatly among the breeds. Some dogs shed year-round, some "blow" seasonally, some do both, and some shed hardly at all. If you're a neatnik, you'll need to either pick a low-shedding breed or relax your standards. To help keep your home a little cleaner, you can find a great de-shedding tool here!

Drooling Potential
2
Drool-prone dogs may drape ropes of slobber on your arm and leave big, wet spots on your clothes when they come over to say hello. If you've got a laid-back attitude toward slobber, fine; but if you're a neatnik, you may want to choose a dog who rates low in the drool department.
Easy To Groom
4
Some breeds are brush-and-go dogs; others require regular bathing, clipping, and other grooming just to stay clean and healthy. Consider whether you have the time and patience for a dog who needs a lot of grooming, or the money to pay someone else to do it.
General Health
3
Due to poor breeding practices, some breeds are prone to certain genetic health problems, such as hip dysplasia. This doesn't mean that every dog of that breed will develop those diseases; it just means that they're at an increased risk.
If you're adopting a puppy, it's a good idea to find out which genetic illnesses are common to the breed you're interested in. You may also want to ask if your shelter or rescue has information about the physical health of your potential pup's parents and other relatives.
Many health problems are related to digestion and issues in the gut. Adding Bernie's Perfect Poop digestion support treats to your dog's routine can help your pet feel better and improve their overall health!
Potential For Weight Gain
4
Some breeds have hearty appetites and tend to put on weight easily. As in humans, being overweight can cause health problems in dogs. If you pick a breed that's prone to packing on pounds, you'll need to limit treats, make sure they get enough exercise, and measure out their daily food servings into regular meals rather than leaving food out all the time.
Ask your vet about your dog's diet and what they recommend for feeding your pooch to keep them at a healthy weight. If your dog has tummy troubles, adding Bernie's Perfect Poop digestion support treats to their diet can help your dog feel better and improve their overall health!
Size
2
Dogs come in all sizes, from the world's smallest pooch, the Chihuahua, to the towering Great Dane, how much space a dog takes up is a key factor in deciding if they're compatible with you and your living space. Large dog breeds might seem overpowering and intimidating, but some of them are incredibly sweet! Take a look and find the right sized dog for you!
Many larger dogs are prone to joint issues. Adding Glyde Mobility Chews to their routine can help their joints stay healthy.
Trainability
Easy To Train
4
Easy-to-train dogs are more adept at forming an association between a prompt (such as the word "sit"), an action (sitting), and a consequence (getting a treat) very quickly. Other dogs need more time, patience, and repetition during training.
Many breeds are intelligent but approach training with a "What's in it for me?" attitude, in which case you'll need to use rewards and games to teach them to want to comply with your requests. Here are some great treats that can actually improve your dog's digestion to get you started!
Intelligence
4
Dogs who were bred for jobs that require decision making, intelligence, and concentration, such as herding livestock, need to exercise their brains, just as dogs who were bred to run all day need to exercise their bodies. If they don't get the mental stimulation they need, they'll make their own work--usually with projects you won't like, such as digging and chewing. Obedience training and interactive dog toys are good ways to give a dog a brain workout, as are dog sports and careers, such as agility and search and rescue.
Potential For Mouthiness
3
Common in most breeds during puppyhood and in Retriever breeds at all ages, mouthiness means a tendency to nip, chew, and play-bite (a soft, fairly painless bite that doesn't puncture the skin). Mouthy dogs are more likely to use their mouths to hold or "herd" their human family members, and they need training to learn that it's fine to gnaw on chew toys, but not on people. Mouthy breeds tend to really enjoy a game of fetch, as well as a good chew on a toy that's been stuffed with kibble and treats.
Prey Drive
4

Dogs who were bred to hunt, such as Terriers, have an inborn desire to chase--and sometimes kill--other animals. Anything whizzing by, such as cats, squirrels, and perhaps even cars, can trigger that instinct. Dogs who like to chase need to be leashed or kept in a fenced area when outdoors, and you'll need a high, secure fence in your yard. These breeds generally aren't a good fit for homes with smaller pets that can look like prey, such as cats, hamsters, or small dogs. Breeds that were originally used for bird hunting, on the other hand, generally won't chase, but you'll probably have a hard time getting their attention when there are birds flying by.
Tendency To Bark Or Howl
3
Some breeds sound off more often than others. When choosing a breed, think about how often the dog vocalizes with barks or howls. If you're considering a hound, would you find their trademark howls musical or maddening? If you're considering a watchdog, will a city full of suspicious "strangers" put your pup on permanent alert? Will the local wildlife literally drive your dog wild? Do you live in housing with noise restrictions? Do you have neighbors nearby? Then you may wish to choose a quieter dog.
Wanderlust Potential
3
Some breeds are more free-spirited than others. Nordic dogs such as Siberian Huskies were bred to range long distances, and given the chance, they'll take off after anything that catches their interest. And many hounds simply must follow their noses--or that bunny that just ran across the path--even if it means leaving you behind.
Physical Needs
Energy Level
4
High-energy dogs are always ready and waiting for action. Originally bred to perform a canine job of some sort, such as retrieving game for hunters or herding livestock, they have the stamina to put in a full workday. They need a significant amount of exercise and mental stimulation, and they're more likely to spend time jumping, playing, and investigating any new sights and smells.
Low-energy dogs are the canine equivalent of a couch potato, content to doze the day away. When picking a breed, consider your own activity level and lifestyle, and think about whether you'll find a frisky, energetic dog invigorating or annoying.
Your dog's energy level can also be affected by health issues. Adding Bernie's Perfect Poop digestion support treats to your pet's diet can help them feel better and improve their overall health!
Intensity
3
A vigorous dog may or may not have high energy, but everything they do, they do with vigor: they strain on the leash (until you train them not to), try to plow through obstacles, and even eats and drinks with great big gulps. These dynamos need lots of training to learn good manners, and may not be the best fit for a home with young kids or someone who's elderly or frail. A low-vigor dog, on the other hand, has a more subdued approach to life.
Exercise Needs
4
Some breeds do fine with a slow evening stroll around the block. Others need daily, vigorous exercise, especially those that were originally bred for physically demanding jobs, like herding or hunting.
Without enough exercise, these breeds may put on weight and vent their pent-up energy in ways you don't like, such as barking, chewing, and digging. Breeds that need a lot of exercise are good for outdoorsy, active people, or those interested in training their dog to compete in a high-energy dog sport, such as agility.
Even older dogs need exercise, and it can help fight symptoms of arthritis and other age-related conditions. Adding Glyde Mobility Chews to your dog's routine can give your dog the joint supplements they need to stay active well into old age.
Potential For Playfulness
5
Some dogs are perpetual puppies -- always begging for a game -- while others are more serious and sedate. Although a playful pup sounds endearing, consider how many games of fetch or tag you want to play each day, and whether you have kids or other dogs who can stand in as playmates for the dog.
You may want to consider adopting an older dog. Seniors can remain playful well into old age and have fewer demands than young dogs. Adding Glyde Mobility Chews to your senior's routine can help fight the symptoms of arthritis and keep your old dog active and playful.

- Cav-a-Jacks and kids get along great together. You should still supervise play sessions between all kids and dogs.
- In general, Cav-a-Jacks are not usually the best fit for a household with an existing cat. They can often view felines as prey to chase.
History
As a newer mixed dog breed, there isn't a whole lot of concrete information about the Cav-a-Jack's history. But looking into the background of the parent breeds, you can get a solid sense of where the dog comes from.
The Jack Russell Terrier began as a small game hunter dog, where the breed's tenacity and high energy made them a big hit. On the Cavalier King Charles Spaniel side, this is a breed with noble roots who was originally bred to be a companion dog for royalty. It's said that King Charles I and II actually gave the breed their name!
The Cav-a-Jack has become known as a designer dog breed, but many of them unfortunately end up in shelters. So consider contacting your local rescue groups and shelters if you're thinking about adding the Cav-a-Jack to your home.
Size
The Cav-a-Jack is a small dog. As is always the case with newer mixed dog breeds, exact size standards might vary.
Most weigh in at 13 to 18 pounds and range in height from ten to 17 inches. Female Cav-a-Jacks can be noticeably smaller than their male counterparts.
Personality
When it comes to the Cav-a-Jack's personality, you can think of this mixed breed as like a small, energetic, and curious child. They will always take up the option of a play session; although, due to the breed's smartness, you'll want to vary things up and definitely include smart toys in their day-to-day environment.
Balancing out the mixed breed's playful side, they also love to be around people--the Cav-a-Jack is definitely a dog who will become a great companion for young and old people alike. In fact, this is not a dog to be left alone all day. Make the Cav-a-Jack a key part of your family and you'll find yourself living with a great dog.
As a heads up: The Cav-a-Jack does have a feisty and independent side, so you'll need to ensure that proper training takes place right from the start!
Health
Cav-a-Jacks are generally considered to be healthy dogs; although, the mixed breed can be predisposed to some of the same conditions that the Cavalier King Charles Spaniel and Jack Russell Terrier face. As always, it's important to schedule regular wellness visits with your dog's vet.
Some of the more common health problems Cav-a-Jacks suffer from include:
- Cataracts
- Lens Luxation
- Deafness
Care
Despite their small size, the Cav-a-Jack is a dog with high energy and exercise needs. Try and aim for at least an hour a day in terms of exercise, and make sure that walks are on the brisk side. Definitely add fetch games and agility tasks to your outdoor routine.
If you have access to a safe dog park, you'll find that your Cav-a-Jack absolutely loves playing around with the other pups! Be cautious if you have a yard: The mixed breed's curious nature means that they could very well attempt to escape through any holes in a fence.
It's imperative that you look after your Cav-a-Jack's teeth. You'll need to brush them a few times a week--ask your regular vet to recommend a breed appropriate toothpaste.
Due to the Cav-a-Jack's love of outdoor play sessions, you'll also want to check their ears for any signs of dirt or potential infection. The dog's nails will also need to be trimmed twice a month--ask your vet to show you how if you're new to dog grooming.
Feeding
An ideal Cav-a-Jack diet should be formulated for a small dog with high energy.
Cav-a-Jacks need to stick to a heathy diet as overeating can cause weight gain and associated health problems, especially if adequate exercise isn't offered.
As with all dogs, the Cav-a-Jack's dietary needs will change from puppyhood to adulthood and will continue to change into their senior years. You should ask your veterinarian for recommendations about your Cav-a-Jack's diet, as there is far too much variation among individual dogs--including weight, energy, and health--to make a specific recommendation.
Coat Color And Grooming
The Cav-a-Jack's coat is often predominantly white, with extra markings that may be tan, black, and brown.
Their coat is short and sometimes a little bit wavy to the touch. You'll want to commit to weekly brushing sessions, and feel free to up the frequency during the months when greater shedding occurs. This will help keep the coat smooth and clean and ward off the chances of mats developing. In terms of bathing, use your eyes and nose to find out if it's necessary, and treat the dog to a bath after any extra dirty outdoor play sessions.
In general, the Cav-a-Jack is an adaptable dog when it comes to climate. But be careful to kit your dog out with a fashionable canine coat if it's particularly cold outside, and always provide fresh water and shade during the hotter months.
Children And Other Pets
Cav-a-Jacks and kids get along great together. The breed is playful and sociable. Don't be surprised if your Cav-a-Jack and your kids become best play buddies. Just make sure that proper socialization takes place at an early age so both parties know their boundaries, especially if your Cav-a-Jack displays a strong independent streak.
In general, Cav-a-Jacks are not usually the best fit for a household with an existing cat. They can often view felines as prey to chase. So ensure that boundaries between the dog and other household pets are set early and supervise interactions.
Ultimately, early socialization really pays off with this breed. Make sure to reward your Cav-a-Jack for good behavior and adhere to a proper training regimen when you bring them home to your family.
Rescue Groups
It may be hard to find a breed-specific rescue for Cav-a-Jacks because they are a mixed breed. However, you may want to try Cavalier King Charles Spaniel or Jack Russell Terrier breed-specific rescues, as they often care for mixes, as well. Here are some rescues you can try:
