Have you tried UDDER Cream. My springer is going through an allergy issue at present. She is eating her feet and constantly cleaning her bottom. Her pads were very dry and splitting so I tried the UDDER cream and within a couple of days they were much improved. You can get it on Amazon. The company is Battle, Hayward &Bower Ltd, Crofton Drive, Lincoln, LN3 4NP. UK. Maybe try on a small area to start with. Hope this helps 😊
