So its been just over a week and my poor baby has stopped using one of his back legs. He is about a year and half. I have looked all over his paws and felt along his leg and cant figure out why he is limping. He sometimes will apply pressure on his leg and put usually just holds his leg up. He seems to be in no pain. He has not made a single cry about it even when I massage his leg. I will be taking him to the vet in the next few days but was hoping I could get some help so I wont be shocked by any results... thanks for any input.
