Hi Maia1234,
Well historically (i.e. the last 4 years) he has always taken excellent care of the dog. Even when he has been really broke he would feed the dog before himself.
So judging by that dog should be OK. I don't know the answer though.
Plus it's his dog.
He isn't a mean or abusive addict. He is a functioning addict.
I hope that they are both OK.
