Thanks for your kind replies

Do you mean the cone Goldenretrlver? I don't think a cone will work, because the wound is very far down her leg and I think she could still reach it Unless they have super big ones lol

Have you bathed Leather?
She hasn't had a bath for a while..But I think that might make it worse Baths dry out the skin, and she has very bad skin problems and allergies...The lake water is probably what made her want to chew her leg again...She does have the chewing disorder (brought on by her boredom disorder) but I don't think that she did this out of bordeom...I think the lake water made it itch
