hi apache my pup is 5 months now and gettin real big ! Ive noticed he has a limp on his front leg his right one. Ive had a good look at his paw and cant see anything in it .he doesnt yelp when i move his leg around either. He is a german shepherd, he normaly has 2 small walks a day just round the block and on the local field, ive cut it down to just one now to see if it helps. Apart from the limp hes a happy pup.
