One day I got a call from DH to check my e-mail. There was this photo of a fur baby named Brutus. He was 4.5 months old and only weighed about that much. After questioning who this baby belonged to hoping some one else, I truly realized DH adopted/rescued him. DH saw Brutus thrown from the back window of a car going down a heavily traveled (semis and dump trucks) industrial road. It was almost day's end. So after work, I headed over to pet smart an got housekeeping and supplies for our new addition. Collar and leash, couple chew toys, crate, food and water bowls. As soon as DH got home with the little guy (he was not allowed in the house yet) he was dressed with his collar and leash and immediately walked to his business part of the backyard. He had a lot of business to take care of and didn't seem to mind the leash. When we thought he was done we brought the 2 girls out for an introduction in the front yard. They are never allowed in the front off leash. So this is the neutral/ introductory area. They played an socialized for about 15- 20 minutes. We gradually took them to the backyard and they did well. Then we took them inside. Got him all settled and fed them all while they were in there kennels. He had a couple accidents but was immediately put on leash and taken outside. He thinks he's alpha male. We've had him since "08". Crate training is the best and easiest. Since he was still a pup he had plenty of chew toys. Couple years ago Brutus was frightened by a Turkey buzzard. I saw what happened. It came in the backyard (the other 2 were there also) and swooped down almost getting him but Bianca the largest actually fended the bird away from him. She almost got hold of the bird. He goes to the backyard to do his business still but if he sees a large bird he gets very close to the fence and so does the girls. Get them used to collar and leash. You can make it out of scrap material for pups like yours. Let them also get used to a leash by letting them drag it around the house.
