Which Dog Breeds Have The Worst Teeth?

February is Pet Oral Healthcare Month and we here at DogTime have some great tips on how to take care of your pup’s pearly whites. Taking care of your dog’s mouth is important not just to fight uninviting breath, but also because dental diseases can be associated with other health issues, such as sinus infections, diabetes, cancer, and a host of other problems. Feel like your pup has less-than-perfect chompers? Your dog may be a breed known for dental health issues. Here is a look at breeds and types of dogs that tend to have more oral health issues than others.

The Chihuahua can be a pretty resilient pup! Being a smaller dog, a healthy chihuahua’s average lifespan can be anywhere between 12-15 years. Unfortunately, their cute, adorable size means they also have smaller mouths. Teeth overcrowding is a problem that many chihuahuas face, often resulting in an adorable snaggletooth or underbite of sorts. This adorable overcrowding could lead to pain and swelling in the mouth

2. Yorkshire Terrier

Did you know the term “Yorkie breath” was coined due to the breed’s infamous halitosis? The Yorkshire Terrier breed is prone to tooth decay, and they are vulnerable to the effects of plaque and tartar buildup. Mouth infections can easily set in with these little pups. If you have a Yorkshire Terrier, it may be wise to start brushing up

3. Toy And Smaller Breeds In General

Many veterinarians report that toy dogs are some of the biggest clients when it comes to chronic bad breath. Plaque and tartar tend to build up quickly in smaller mouths and should be addressed. Other small pups known for their not-so-lovely breath include smaller Poodle mixes, Pomeranians, Cavalier King Charles Spaniels, Malteses, and Italian Greyhounds. These smaller breeds are also prone to tooth decay and gum diseases.

4. Brachycephalic (Short-Faced) Dogs

Brachycephalic dog breeds include the Brussels Griffon, English and French Bulldog, Shih Tzu, and Pug. Who doesn’t love these adorable short-faced pups? Well your wallet may not after the extensive dental work these breeds may need. Short-faced dogs are more prone to periodontal disease. This gum disease can lead to some serious pain and bad breath for your dog. If you have one of these breeds, be sure to get their teeth cleaned regularly and give them quality chew treats–maybe even make your own

5. Shetland Sheepdogs

Due to its long, slender muzzle, the active Shetland Sheepdog, or Sheltie, can be prone to a host of genetic dental issues. Abnormal bites and incisors can be common in this herding breed. Also due to genetics, this breed is also known to sometimes be completely missing a few teeth. If you really want a Lassie in your life, be sure that you are ready for the toothy-issues that may arise.
