>>My Min Pin Bruiser will be one year old on Jan 31st 2007.
>>Since he was approximately 7 months old he has been occasionally favouring his back left leg. It is a reoccurring problem that comes and goes, i have noticed it perhaps 5 to 6 times in the last 5 months.
>>I have had x-rays done on the leg and there is no noticable bone issues, other then a slightly loose kneecap my vet says she can feel, which could be popping in and out on his own and causing inflammation, which in turns causes him pain. he sometimes whines a little when hes favouring his leg but it is rare, usually he just holds it up for awhile.
>>Has anybody else experienced this? My fiancee thinks it maybe a tissue or ligiment issue as he is extremely active and loves to jump from the beg, couch, etc.
>>If anybody has any idea what could be casuing this do you also have an idea of what i can do to make it better for him?

The knee problem--luxating patella--IS a connective tissue problem. Favoring one side can cause injury to the other side. Certainly a dog can be injured from jumping off furniture, injury that is highly common in small dogs. The solution to that is to get the dog a ramp and teach him to use it at all times for getting up and down from furniture.
When a dog actually takes weight off a leg, it likely needs treatment. Another thing that doesn't show on x-ray is knee ligament injury, and this is epidemic in American dogs because of all the extreme activities people are doing with their dogs. It requires surgery for the best chance of avoiding the otherwise-inevitable arthritis developing in it later.
Dogs don't show pain much, so his not putting weight on the leg is a huge sign. I would restrict his activity at least during these times--that means NO running and NO jumping.
It is very important with any dog in any condition to handle retrieving and similar games in such a way that the dog never jumps up and lands on just the hind legs. People love to watch this athletic-looking behavior, but it can horribly cripple a dog. They are not built to land that way. When anyone throws a toy for a dog, it needs to to in such a way that the dog doesn't jump up so high and also doesn't twist the body. One way to avoid such moves is to restrain the dog from going out for the fetch until the object has landed. But for the limping dog, no running.
Surgical specialists are usually the best vets to do these surgeries. I'd suggest you ask your vet to refer you to a specialist now for evaluation, before the dog does further damage to the joint.
