Dog growling at one year old

Alex

Hi guys! We recently took in my BIL’s dog. We suspect that there was some abuse towards him going on at the hands of my BIL and his wife. We have a one year old. She doesn’t touch him or even get within 3 feet of him the majority of the time. Recently the dog has started growling at DD if she even just looks at him. I promise she does NOT mess with him ever, so him growling at her for looking at him concerns me. Is there any way to correct this behavior? We have known this dog for a long time and my husband even took care of him for a couple of years before I came into the picture and he has never exhibited this type of behavior, which is why we took him in. We didn’t suspect any abuse until after he came into our home. Any tips or advice would be appreciated! I just want everyone safe. Obviously our daughter comes first.
