I have always kept a leather collar on Ellie, except at night when I take it off. They've always been quite sturdy types; it is hard to find a plain leather collar that I like that doesn't cost the earth, so am sometimes reduced to buying collars made for slightly larger dogs! As you might remember Ellie has had a funny skin irritation on her neck and inner elbows which seemed to last just 24 hours and then mysteriously disappeared. Well, ever since that time last week I have noticed that the fur around her neck, mainly on the under-side, is thinner. I am thinking perhaps it could be something to do with the collars? I dont know and am begining to worry it might not grow back! She hasn't had a collar on for a week now, I thought I'd give her neck a rest. Do any of you have any ideas or advice? I really need your help!
