Kevin has been having some problems with his paws (one of many things). He currently eats a diet of beef. He’s been on it for about 4 months so I don’t think it’s that. They are so red and swollen. I did try to clean them and used NuStock but it made them so much worse. He’s struggling to do the stairs because of how sore they are. Does anyone have any tips? Or know what could be causing it?
