I was wondering if you guys might have some advice I could pass along to my friend. She recently rescued (from a no-kill sanctuary) 2 min pins (brothers). I think there background wasn't a good one; possibly some abuse. They are afraid of people (but are getting better); one in particular is afraid of men. She is trying to housebreak them without success and also they constantly bark when ever people come around them. She was thinking of obediaence classes but I didn't think that was the right thing for them right now. Any advice?
