Hi everyone! I know I have been gone awhile. Summer has been so busy! Anyway on to my question...Despite Rex's flea treatment, he got bit by one on his leg at his knee. It started out a bump and then he chewed until it bled. After it scabbed, he started chewing it again. It has been a week and he keeps reopening the scab and causing it to bleed again. We have tried bandaging him up with gauze and then taping it like a cast and he just chews that off. I have also given him plenty of other things to chew on other than his leg and nothing is working. What can I do to get him to stop long enough for this sore to heal?
