A friend of mine contacted me today asking if I would be willing to adopt his husky, Shadow. I asked why he wanted to rehome him and he told me "I was hard on him as a puppy and he's never trusted me since. He's very skittish and he's starting to bite people now when they reach for him." His wife is still very attached to Shadow so I am looking for ways for my friend to build trust with his dog again. I already told him about dropping treats every time he is near Shadow but he said he has tried that and Shadow refuses to touch them until he leaves the room. When I asked what other things he has tried to build trust he said "the way I treat him, being patient, spending more time with him, going on walks a lot etc. etc." Any other tips that I can pass on?
