@etzbseder:
Well, we are back from the vet. I am told not to worry about the infection I thought he had, it's probably just him growing up and it being mating season. as for his let, he has a swollen knee and I should keep him from stressing it and have him eat 1/4 pill 2x a day of an anti-inflamitory/pain killer, like tylenol (i think).in a week, i will return and see if he is better and if an x-ray is needed.
Hopefully NOT Tylenol..as acetaminaphen is toxic for most dogs. Hopefully it was something the vet perscribed. Is it is his knee (rear leg), or his elbow (front leg). If it is his rear leg, he may have a bad patella. They can pop in and out, the dog can appear to be limping, and then be fine.
