My Siberian husky that is 10 years old in july has been limping and he acts like his front paw gives him problems so he rest his front paw. He whines if he steps on it wrong to. Does anyone know what could be wrong with him? I would take him to the vet but I am divorced and I don't have enough money to take him to the vet. Does anyone know what could be wrong? Please I need to know ASAP
