Riley's vet said he has very slight LP in both knees.....
He said Not to Downplay it but that it is fairly common in a
lot of small breeds...and that most of them live fine with it.
I have never noticed Riley limping or favoring either knee or
anything... I do have stairs for him to limit jumping. And
Weight plays a Huge factor..... which is one of the reasons I
switched Riley's food and am taking him on more walks....
he needs to lose 1 pound..... probably a little less than that, now...
Hope this helps!
