Cockapoo : Health

The notion of hybrid vigor is worth understanding if you're looking for a Cockapoo. Hybrid vigor isn't necessarily characteristic of mixed breeds; it occurs when new blood is brought in from outside the usual breeding circle--it's the opposite of inbreeding.

However, there is a general misconception that hybrid vigor automatically applies to mixed breeds. If the genetic pool for the mixed breed remains the same over time, the offspring won't have hybrid vigor. And if a purebred breeder brings in a dog from an unrelated line, those puppies will have hybrid vigor, even though they're purebred.

Not all Cockapoos will get any or all of these diseases, but
it's important to be aware of them if you're considering this breed.

• Cataracts: Cataracts cause opacity on the lens of the eye, resulting in poor vision. The dog's eye(s) will have a cloudy appearance. Cataracts usually occur in old age and sometimes can be surgically removed to improve vision.
• Patellar Luxation: Also known as slipped stifles, this is a common problem in small dogs. The patella is the kneecap. Luxation means dislocation of an anatomical part (as a bone at a joint). Patellar luxation is when the knee joint (often of a hind leg) slides in and out of place, causing pain. This can be crippling, although many dogs lead relatively normal lives with this condition.
• Hip Dysplasia: This is an inherited condition in which the thighbone doesn't fit snugly into the hip joint. Some dogs show pain and lameness on one or both rear legs, but others don't display outward signs of discomfort. (X-ray screening is the most certain way to diagnose the problem.) Either way, arthritis can develop as the dog ages. Dogs with hip dysplasia should not be bred--so if you're buying a puppy, ask the breeder for proof that the parents have been tested for hip dysplasia and are free of problems.
• Allergies: Allergies are a common ailment in dogs, and the Cockapoo is no exception. There are three main types of allergies: food allergies, which are treated by eliminating certain foods from the dog's diet; contact allergies, which are caused by a reaction to a topical substance such as bedding, flea powders, dog shampoos, and other chemicals; and inhalant allergies, which are caused by airborne allergens such as pollen, dust, and mildew. Treatment varies according to the cause and may include dietary restrictions, medications, and environmental changes.
• Liver Disease: This condition is becoming more prevalent in Cocker Spaniels in two forms: chronic active hepatitis and copper toxicosis (poisoning). Both conditions may or may not be genetic; at this point no one is certain. More research is needed, but meanwhile ask your Cockapoo breeder about the parent Cocker's liver history.
• Ear Infections: These afflictions may plague the Cockapoo because of his floppy Cocker ears, which can trap moisture, dirt, and debris. The Cockapoo's ears should be regularly checked and cleaned. Ask your veterinarian about appropriate ear care products.

In Cockapoos, you should expect to see health clearances from the Orthopedic Foundation for Animals (OFA) for hip dysplasia (with a score of fair or better), elbow dysplasia, hypothyroidism, and von Willebrand's disease; from Auburn University for thrombopathia; and from the Canine Eye Registry Foundation (CERF) certifying that eyes are normal. You can confirm health clearances by checking the OFA web site (offa.org).

Health clearances are not issued to dogs younger than 2 years of age. That's because some health problems don't appear until a dog reaches full maturity. For this reason, it's often recommended that dogs not be bred until they are two or three years old.
