What is Canine Hip Dysplasia?

Canine Hip Dysplasia is a hereditary, degenerative disease common in many large breed dogs and large mixed breed dogs that can cause crippling arthritis in the hips. This disease is especially prevalent in German Shepherds; the Orthopedic Foundation for Animals notes that one in five German Shepherds whose hips are x-rayed and reported to the OFA show signs of the disease.

Normal hip joints function with a “ball-and-socket” construction; the head of the femur, or thigh bone, fits tightly within a circular inlet in the pelvis.

In dogs who are suffering from hip dysplasia, the ball does not fit snugly within the socket; the head of the femur can be shaped incorrectly, or be a loose fit with the pelvis, or both. This condition causes unusually heavy friction on the joint as the dog moves, which in turn can lead to osteoarthritis, a painful inflammation of the joint.

Hip dysplasia is rated by the Orthopedic Foundation for Animals as mild, moderate or severe (there is also a “borderline” category, which indicates the dog is capable of developing hip dysplasia). Dogs with hip dysplasia can show few symptoms, or become incapacitated, depending on the severity of the dysplasia, the progression of arthritis, and environmental factors such as weight and exercise level. Although surgical options are available for severely affected dogs, these are often expensive and are accompanied by a long recovery period.

Hip dysplasia is almost always evident by the time a dog is 18-24 months old. There is no way to declare a dog free from hip dysplasia, or diagnose hip dysplasia, without hip x-rays.

The most common visible signs of hip dysplasia include difficulty rising, stiffness or soreness following heavy exercise, a distinct gait in which the back legs move together rather than independently, and reduced muscle mass around the hips and thighs. Some severely affected puppies will develop a limp before they’re five months old; to the untrained eye, this limp appears to be on a forelimb, rather than hind, as might be suspected with pain in the hip joints.

Maintaining a dog with hip dysplasia requires attention to nutrition, weight, exercise and activity levels. Check with your veterinarian regarding medical options, including surgery or anti-inflammatory drugs.

Debunking Dog Myths

You think you know your dog? See if your dog has been subject to any of these popular canine myths.

Talk to anyone from your next-door neighbor to your cousin who shows dogs, and you’ll hear a variety of interpretations on dogs and dog behavior. Some of the most common myths I hear regarding our canine friends are debunked below.

German Shepherds may have some wolf-like characteristics, but rest assured they are 100 percent domesticated dog.

Myth: Dogs are essentially wolves.

Because science tells us dogs are direct descendants of wolves, animal behaviorists and dog trainers assumed for a long time that dog and wolf behavior are interchangeable. We now know this is not the case. Biologists now hypothesize dogs are not pack animals, but semi-solitary scavengers, and do not form social hierarchies the same way wolves do.

Using “alpha rolls” or other forceful techniques in an attempt to thwart perceived “dominant” behavior is unecessary, and is often seen by dogs as an act of aggression.

The Monks of New Skete, who popularized the wolf-to-dog culture trend in their book, “How to Be A Dog’s Best Friend,” have since omitted such training suggestions in the book’s revised edition.

Top animal behaviorists, including Ian Dunbar, Jean Donaldson, Patricia McConnell and Karen Pryor, agree solid leadership is best achieved by controlling the dog’s access to resources without resorting to the use of force.

Myth: Dogs want to please.

This is not entirely untrue. Dogs DO want to please – themselves. Dogs are exceedingly selfish. They do what they do because making us happy means they get more of what they want – attention, food and freedom.
Our mistaken belief in dog altruism is why we are so perplexed when the dog uses a behavior we DON’T like — such as jumping up, barking or digging — to get what it wants.

The good news: You can use this ubiquitous doggie trait to your advantage by controlling the dog’s environment and the consequences of its behavior. For example, if the dog is getting in the trash, you can confine the dog or confine the trash. Or if you’d like the dog not tear the door off its hinges as it goes out, you can request a sit from the dog before opening the door.

Myth: Dog training takes lots of time.

Teaching your dog new tricks takes lots of consistency, and a little time. Breaking bad habits takes more consistency, and a little more time. Every interaction you have with your dog is a training situation. When the dog paws at your leg and you absentmindedly reach down to pet it, you are training. When the dog lies quietly at your feet while you watch TV and you absentmindedly reach down to pet it, you are training.

The key to teaching good habits and breaking bad ones is to not be absentminded around your dog! Be consistent and be aware, and the training will take less time than you think. To borrow from top K-9 trainer Steve White: Remember that training is taking place until either you or the dog achieves room temperature.

Myth: An aggressive dog is a protective dog.

Aggressive dogs, simply put, won’t tell friend from foe. Dogs, in most cases, are much less adept at reading human intentions than we’d like to believe. My dogs bark wildly every time I return home, despite repeated admonishments of, “It’s STILL me!”

An aggressive dog is much more likely to threaten or injure you, your family, neighbors or friends than it is to ward off intruders. If you want a dog for protection, go out and get the biggest, happiest dog you can find, then train it exceedingly well in obedience. Would-be bad guys won’t want to find out what else the dog knows, and you won’t have to worry about the dog misfiring on you, your family, friends and other animals.

Myth: Dogs don’t have feelings.

Well, anyone who’s ever looked into those adorable, deep brown eyes knows this isn’t true. But science is finally catching up to the fact that dogs and other animals, while not expressing the emotional range we recognize in humans, are sentient creatures. The Economist in February reported that new scientific research is beginning to shake tradition to allow for the recognition and documentation of animal emotions. Personality aspects distinctive to dogs were labeled “sociability,” “affection,” “emotional stability” and “competence,” in studies by Samuel Gosling at the University of Texas in Austin.

Dr. Gosling’s conclusions will allow behaviorists to better understand individual animals’ personality differences, while giving dog owners one more reason to refer to their pets as members of the family.

Five reasons to avoid invisible fencing for your dog

Reasons I discourage boundary training any dog using an invisible fence, especially a German Shepherd:

    • You still have to train the dog. Many people assume an invisible or underground fence is “plug ‘n’ play” — that is, you simply install it, plop the collar on your dog, and let him play to his heart’s content. This is not the case (as the reputable underground fence dealers will tell you). The dog still must be trained to accept the fence’s boundaries. But the assumption that it is an “easy” way to contain a dog makes me question whether the potential owner is really willing to put effort into the dog’s care and training (i.e., regular walks, obedience), as well as make sacrifices (e.g., increased cost and imperfect landscaping) to accommodate the dog.
    • Electric shock. As far as I know, all varieties of invisible fencing operate on the premise that the dog wears a collar which produces electric shock when the boundary line is approached. Some dogs are so determined to make it through the fence that the shock level must be turned up unusually high. I have seen instances in which a dog wearing a fence collar was inadvertently shocked by the owner’s television, computer or vacuum. (Think of how healthy this is for the poor dog’s mental state!) I have also heard horror stories and seen pictures of third-degree burns caused by fence collars that have malfunctioned. Beware of the underground fencing dealer who tells you this can’t/won’t happen — after all, he’s there to sell you something, not to look out for your dog’s well-being. That’s your job.
    • Dogs can — and will — go through an invisible fence. And once they do, guess what? They won’t come back into the yard for fear of getting shocked; they aren’t stupid. They’re simply willing to take the shock the first time through to get whatever they’re after. And once they’re through, they’re free to chase other animals, get into fights, get hit by cars, be shot at, picked up by animal control, etc.
    • Underground fencing does not keep anyone from entering your property. Therefore, children, cats, other dogs, wild animals and the like are free to come onto your property and tease or terrorize your dog. And dog thieves find underground fencing absolutely delightful — all they have to do is take the collar off the dog and go!
    • This study linking use of or malfunctioning of underground fencing to serious biting incidents. Do we really need to make our dogs more subject to lawsuits and breed-specific legislation? Further reading: “Train With Your Brain” — Green Acres Kennel

Keep in mind this is my reasoning, and there are plenty of responsible rescuers/breeders who will place dogs in homes with invisible fencing. Also understand that a “real” fence can be a hallmark of lazy or irresponsible dog ownership and is certainly not a cure-all. But given the fact that regular exercise can eliminate the need for a fenced yard (a luxury) and given the variety of fencing options available, I’m inclined to turn down prospective homes who insist on invisible fencing, for the reasons listed above.
