One of our dogs has become very uneven on his legs. He seems to have had noticeable pain on both his front legs and his gait is very odd. I've felt for heat and swelling, but haven't found anyithing. I've checked his pads for splinters, again nothing. I'm wondering if it's something neurological. Our baby was lame on one of his forelegs, and seems better on rest and recouperation. This ddog is 12, had massive problems with balance and concentration as a youngster. He doesn't seem to be in acute pain and has not had signs of arthritis. He's going to the vet next week. I am concerned that his condition could deteriorate over the weekend. Any ideas?
