For the last 5 days my dog has been limping on his front leg, he is a beddlingtonXwhippet and 9 months old, I dont know how he done it he just started limping, sometimes he doesn't sometimes he does, since I noticed it I have just taken him for short walks on the lead but it is driving him mad he needs to burn up energy (so do I), there is no swelling or redness anywhere but one of his paws does feel a little bit warmer than the other, I had another Lurcher who got a knocked up toe and I knew when he done it because he squealed alot, I was wondering if he had a thorn in it, has anyone got any
