My name is Brutus!

Hello, we are looking for a welcoming home for Brutus. We acquired him through a rescue farm where his litter was dropped off. The lady told us that Brutus's mom looked like a beagle and border collie mix, however we do not know what breed the father is. We have had him for almost a year. He is really good with kids and very playful because he just turned 1. He is a large dog and just got neutered about 3/4 weeks ago, so these pictures are before hand. Before he got neutered he started becoming more aggressive towards the other dogs (mostly our other male dog) in the house protecting the kids. He needs a home that he can run around and play. He is very sweet when he is by himself and thinks he is a lap dog. He is trained to go to the bathroom outside, kennel trained, and he knows how to sit on command. We are also expecting another child and would not be able to give him the attention that he requires. We are also living with family right now so the house is very crowded.
