I noticed Sam was walking funny last night and saw him chewing at his claws several times. I checked his pawpads out and between his toes and found nothing. This morning I picked him up for a hug and his front leg is swollen. I called the vet and the only way he can be seen today is if I drop him off which I cant do because he gets way too upset to be left there all day by himself. I called the other 3 vets in town and got the same story, booked solid until Monday. He isnt limping on it but walking like hes stiff-legged. I cant think of anything he could have done out of the normal that would hurt his leg. I dont know what to do for him and waiting until Monday is terribly upsetting to me.
