My oldest boy George is 2 years old. He developed foot spurs on both of his front paws about 6 months ago. I've been clipping them back every time I do his nails. Yesterday when I was doing it I noticed that the pads of both front paws now have a few cracks in them. Is this likely to be connected to the spur problem? Do I need to bring him to the vet? I don't think the paws are sore because he didn't complain anymore than usual.
