Couple days ago, this thing showed up on Rosey's foot, and I couldn't for the life of me figure out wtf it was. The day I noticed it, I sprayed it with Bactine, put some gauze on it and then wrapped it up. Next day, I took off the wrap and it looked better, because she wasn't able to chew on it. Yesterday, I get home from work and she had been chewing/obsessively licking it, and it was back to looking gross. See my brother today and he's like "oh yah, I know how she got that. I was walking her, the leash got wrapped around her foot, she panicked and pulled. It's rope burn". Great. Other than keeping it clean, and putting her in the cone of shame so she can't bug it, anything else I should be doing?
