Hold off on the bath. Before you bring him into the house walk him around your nhrhgboieood so he can get used to the area and the smells. Then after about an hour and he's tired out, bring him to your house and take him to HIS' spot in the yard, you're telling him this is where you are permitted to pee, when he goes, praise lavishly. When done, with your dog still on a leash, enter the house (you first) make him sit (if able) and you walk in the door and then invite your dog inside. With him still on the leash, introduce him to each room, let him sniff around. When entering a bedroom you enter first then invite the dog inside. This lets him know that this is YOUR house and you are LETTING him into it, it establishes you as "Pack Leader" Then show your little friend his place to sleep and his toys. Make sure it's in your room beside your bed so he's not alone at night. Dogs are pack animals and need to be with their pack. Once this is completed, let him off the leash to explore. Give him a few days to settle down in his new environment. Make sure you establish rules and boundaries, if you don't want him on the sofa, make sure he knows it and correct him. He will respect you more as a leader than he will if you allow him the run of the house, and he'll make your life miserable. Is he fully housebroken yet? If he happens to have an accident DO not scold him, simply clean it up and take him outside to his SPOT, praise him when ever he goes outside.Once your dog has settled down to his new house (about a week) then you can attempt to give your friend a bath. Or for the first time take him to a groomers and have them do it.Good luck with your new friend.
