Is this bumble foot? I don't want to treat like it is and pull the scab like thing off and it not be and hurt his foot! He's a rescue and has had these on his feet but just started limping. Is he missing his middle toe, we believe something bit it off (close to where the big scab is) I can only upload one photos so I will attach his other foot photo in the comments, I believe he has it on both feet. He's on azithromycin and metacam. Waiting for booties to come, and tricide neo powder. Soaking in warm Epsom salt.
