My dog has been limping on his left front leg all day and he is very uncomfortable, whining and crying. I can not get him to a vet at this time and I have very little money to have it fixed if it has been dislocated or broken. I did call a Vet in the area and they told me to put a heating pad on it till I can have it seen. Is there anything else I can do to make him more comfortable or give him till I can bring him in to be seen?
