Common sense genetics on slipping patellas, popping hocks, elbow and hip dysplasia in a carnivore genetically programmed for sound joints and strong bones. Read, learn, and then go to VIDEO Theater to SEE how joints and tendons all work.
HOW TO PREVENT BONE-JOINT PROBLEMS
by Barbara J. Andrews, Publisher - TheDogPlace.org
Dogs are genetically programmed for survival. They are born with pre-determined (inherited) color, size, and structure. As hunting carnivores, they would starve with weak ligaments and joints.
It's as simple as that. No amount of x-rays can prevent bone and joint problems or change a dog's genetic predisposition for ii luxating patellas (knees), and dysplastic hips or elbows. DNA tests may reveal genotype but only breeders can control phenotype and only owners can control environment, exercise, and diet.
And that is where breeders and owners most often fail the canine. Bone and joint deformities are usually the result of accelerated growth and/or obesity at any age but they are made worse by lack of exercise and poor diet. Wild carnivores are never, ever obese and in order to survive, they get plenty of exercise.
Only after you've wrapped your mind around that common sense concept, should you listen to the sales hype about genetic markers, DNA tests, X-rays, etc. Tests only tell you what is, not how to preserve it and rarely do they help you prevent it.
Most veterinarians are eager to do those tests but do ever advise you to get the weight off your dog o put him on a treadmill??? And let's face it, only a handful have ever bred a litter and even fewer have produced a show dog or field champion. So... flying in the face of convention and profitability, here's your prescription for soundness.
I know some breeds are more difficult to work with but a Mastiff, Bulldog or Pekingese can be both "typy" and structurally sound. Let's begin by understanding the modern canine.
Medial patellar luxation is common in toy breeds, said to be hereditary (kneecap ligament slips out of the trochlea (groove) towards the inside of the leg). I strongly disagree. I see it as a combination of nutritional factors and pogo jumping which most toy breeds do as a result of environmental factors. Do your toy dogs stand in one place and jump up and down when out in the yard? No. They only do it when fenced, kenneled, or in x-pens.
Lateral patellar luxation is common to large and giant breed dogs (kneecap ligament slips to outside of the leg, causing dog to limp or carry the leg). A shallow groove may be inherited but expression of the problem is dictated by growth rate, muscle strength, and weight. Most large and giant breed puppies are overfed and under-exercised. Roadwork is only for adults. Large grassy paddocks in which to run and play are natural for healthy puppies.
No species is born with bad spinal, hip, elbow, or knee joints
... excluding birth defects which are most often the result of medical interference when the child or animal is in the uterus. Dog breeders usually put more emphasis on features of type than on sound structure and common sense. Forcing puppies into early development is as detrimental to bone and joint health as is substituting fat for substance in order to appear more "mature" in the show ring. No wonder we have an “epidemic” of hip, knee, spinal and elbow problems!
Pushing puppies with grain-based formulations guaranteed to insure maximum growth and development insures bone and joint deformities! As AKC judge "puppies" presenter Pat Hastings points out, we can accelerate bone growth but NOT muscle and tendon development. If your litter develops bowed front legs, stop using that dog food because invisible damage to hips and knees is also occurring.
The last place you should see overweight dogs is in the vet’s office. Dogs that were born with good hips and knees suddenly turn into opportunities for hip, patella, or cranial cruciate ligament (CCL) surgery. Diet food for dogs? Ridiculous! Feed a dog the way nature intended and you will have a structurally sound dog well into old age.
Knee joints meant to hold up 30 pounds can not possibly support 40 pounds of
blubber and flabby muscle!!! Let me repeat that. A Labrador bred to be an active
hunter at 65 pounds can not remain sound at 80 pounds. As a group, most Sighthounds are sound compared to Working
Breeds which are often shown overweight (to give the appearance of substance)
whereas an overweight Saluki wouldn’t be in the ribbons. And what about toy
breeds? What is the incidence of hip and knee problems in Pugs as compared to Miniature
Faulty X-ray Results Based On A Faulty Concept
Dr. Corley (OFA) and I had more than one contentious conversation due to cited inconsistencies and risks associated with the dogma of the day. I also kept up with Gerry Schnelle, DVM (first to report and study hip dysplasia and one of the founding OFA vets) after he publicly resigned from the OFA board. He stated in JAVMA that he could not fairly read an x-ray of a dog he had not seen and evaluated for overall muscular condition, whether the bitch was in estrus, had recently whelped, etc. In years of seminars and columns, Dr. Schnelle and I stressed that hips were only two out of a hundred joints that could cripple a dog. Finally, due to OFA’s declining financial health - the Orthopedic Foundation For Animals began certifying elbows. Having a true dog person at the helm now (Eddie Dzuik) is the best thing that’s happened to OFA.
When Dr. Barden’s fulcrum x-rays became the rage, I exposed the false logic and the associated positioning risk in my newspaper column. This isn’t self-aggrandizement. I offer these references because I have no veterinary degree with which to impress you. My degree is 52 years of in-depth clinical experience and hundreds of top ranked AKC Chs. So when I suggest that nature has an infallible plan (discounting the platypus) and that it is commerce which upsets the balance of canine structure and soundness, I hope you will think about what you are feeding your dogs, their growth rate, weight, and type of exercise.
Now if only someone would invent a kennel run with a retractable low top to prevent dogs from hopping up and down I’d be ever so grateful but until that happens, I’ll continue to apply common sense to feeding, rearing and maintaining my super-sound Toy dogs.
If you have a large dog prone to hip dysplasia (keep him trim) and for more on the risk to both knees and hips visit VIDEO THEATER'S Hip Dysplasia coverage. If you have a "toy" breed dog, be sure to watch Rear Leg Tendons & Patellas to learn about cruciate ligaments and knee caps. Video Theater makes it easy!
