How to Identify Slipping Knee Caps in Small Dogs

Small dogs like toy poodles, pomeranians and boston bulls often suffer from patellar luxation.

Slipping kneecaps, clinically known as patellar luxation, occur when a dog's kneecap slips out of place. This can cause serious pain for the animal and temporary lameness until the kneecap slides back into place. It is particularly common in small dogs and is relatively easy to spot once you know what to look for.

Instructions

1. 

   Check to see if your dog is overweight. Excess weight puts undue pressure on a dog's joints and can cause his kneecaps to slide even if he does not actually have the condition. If you cannot feel your small dog's ribs, then he is likely overweight. Toy breeds and small dogs are often carried around more than they walk, which leads to weight gain. Work with your vet to develop an exercise regimen appropriate for your small dog.

2. Look for a skipping motion when he walks. If the kneecap is slipping only slightly, then it may not show in serious lameness but rather a skipping motion caused by your dog periodically favoring one of his legs.

3. Take note of periodic bouts of lameness. If the condition is more serious, then your little dog may have regular periods during play where she temporarily "goes lame" for ten to twenty minutes. Then, generally before you have figured out what is wrong or taken her to the vet, she will appear to be fine again. This is a strong indication of patellar luxation.

4. Look at the dog's rear legs. If one or both are extended backward and the dog cannot return them to a normal position, the kneecap is out of place. Your little dog will often actually walk on three or even two legs to compensate for this.

5. Watch for a straddle stance. If your dog is experiencing patellar luxation, he may try to prevent it by walking with his legs far away from his body. This will give him a stiff walk and make him look like he is trying to walk over something.

Tips & Warnings

• If you think that your dog is suffering from patellar luxation, take your little pet to the vet immediately. Left untreated, this condition can result in premature arthritis and even total lameness over time.
