I have been looking into adopting another dog for the last month or so after losing my best friend extremely suddenly back in November. She ended up with anti-freeze poisoning, and by the time we realized she was sick, it was far too late. (We still have no idea what happened. Our other dogs have been fine, I walked the fence perimeter multiple times a day every day for two weeks after and never found anything that could have made her sick.)
In our household, we already have three dogs and three cats. The three dogs we have are all bonded to their own particular member of the family, so I was hoping to find a new pet to maybe be that companion that my previous dog was for me for the last nine years.
I went to our local shelter and found two good possible dogs and decided on adopting the younger, more playful of the two. At the shelter, she was incredibly calm and quiet. She played in the visitation room, didn't seem to be aggressive towards the cats outside the room. She seemed like a good dog for our household.
Well, upon bringing her home I started to learn that she is an absolutely endless ball of energy. I have walked her several times an hour, took her to the dog park so she could just run (we have a fence at home, but I haven't introduced her to the other dogs, yet). I even ran her up and down the street several times. She still is full of energy, which is a little more than what I was hoping for. I was hoping for a dog that is playful, but still content to hang out.
The biggest issues, though, are the fact that she has shown aggression to the dogs already living at my house, and the fact that she absolutely cannot even begin to co-exist with the rabbit that lives in my room. When she is in the house, her only goal is to try and tear through the cage to get to my rabbit. Now, my rabbit isn't actually too frightened by her, as my newly adopted dog does not bark. My new dog does, however, bite at the cage to try and get to her. She constantly jumps on the cage (it's a tall wooden hutch), and she absolutely cannot take her mind off my rabbit. If I try to let her explore the house, she runs right back to my room to the hutch. I have pulled her from the hutch, I have stood between her and the hutch, I have yelled at her, tried to keep her mind off of it by trying to play with her with her toys. I have even had her sit on my bed and lay down while I sit between her and the hutch. So far, my only solution is to put her in her crate. Though, she still whines at my rabbit while she's in the crate. I would put her in another room, but we currently do not have a room she can stay in.
While we are out of the house, she is sweet. She's really good with young kids, too! Though, she needs leash training before a kid could walk her. She's not 100% house trained, but she's doing good so far. She also has good manners as far as not begging, goes.
I am entirely conflicted. I feel as if my new dog will be entirely unhappy living in this household. I feel like it also may be stressful to try and keep a dog who is aggressive towards the others, who may not be good with cats, and who is definitely not good with rabbits in my household. I know when I adopted from the shelter, I was going in 'blind' so-to-speak. It is, unfortunately, a kill shelter who does not do any training or behavior tests. They also never get to leave their kennels, for the most part.
This is the very first day so I don't want to give up yet. But every moment she is in my house, but out of her crate, she is trying to get to my rabbit. I have had this rabbit for three years, and it's unfair for me to kick her out.
So in a nutshell, I was hoping to find some advice on what I should do. Should I try to find her a more suitable home where she is really the only pet? Should I keep trying despite the stress?
