Sad Day

So Andrew and I have had a hard decision to make about Roxie our dog. She has been really mean to our children and to any visitors that come over. She bites and growls and has a really bad attitude. On the other hand she always wants to be around me. She loves to sit on my lap and to follow me around the house or the yard. She loves me but annoys me at the same time. So we decided to take her to the animal shelter to see if some one else could take her off our hands. I was feeling pretty bad about it on our drive there and I just knew that I was going to be heart broken that we were getting rid of her. When I got there and they asked me all about her history and if she has ever bitten anyone I told the truth. She has bitten Kodi a few times and broke the skin once. Since that had happened they could not place her in someone elses home. They had to put her down. I am crying my eyes out typing this. I had to muzzle her and there was an employee there trying to help and Roxie just kept trying to bite him and she was growling and bearing her teeth. It was horrible. Andrew was outside in the truck with our sleeping girls. I just wanted to say nevermind, but I have to protect my babies from getting bit. I am really broken up about the whole thing and I made Andrew promise that we will get another dog when our girls are older. I feel so guilty for the whole thing. She totally loved me and I had her killed.
