you can try this it might help but it won't hurt I have been using this on my dogs fo over 20 years i use it for hot spots and it will also help mange. get flowers of sulfur from the drug store and mix in a glass jar a table spoon of sulfur to a tablespoon of criscoe grease, mix well and apply to the affected area 2 x a day. it may be licked off but thats ok. It won't hurt your loved one.
