My 18 year old son adopted a 9 month old Australian cattle dog / blue heeler mix from a dog pound the other day, named Bella. By looking at her, it appears she may have some German shephard mix in there as well. She is very sweet to all of us humans who live in the house, but I am concerned about her behavior toward my 6 lb. chihuahua and his toward her.

The chi is my dog who I have had for over 10 years and I am very attached to. He can get hyper and could growl if he feels threatened but has never bit or attacked another dog. Bella hasn't exhibited any aggression, but we are still trying to get to know her.

My concern is Bella has not growled or shown her teeth, but has made lunges at my chi, especially when he scurries around quickly like chihuahuas do. He can be a fairly active dog. Bella has also lunged at him when she was sitting on the couch with us and he wanted to join us. I am not sure whether this is aggression or another normal dog behavior. When she lunges, we have always been there to immediately tell her "no" and pull her back since we do not know what her intention is. Another thing I have seen her do is reach her front paw/leg out to touch or pat him as he walks by. Because of their size difference, we have not let them "work it out" themselves. I do not want my chihuahua hurt...or worse.

Bella does not appear to be a hyper dog at all, especially for being less than a year old. But she is new to our household and is still recovering from being spayed so we may not have necessarily experienced her actual personality yet. She appears to have had some sort of training. She is house broken and knows to sit and shake her paw. The one behavior I have noticed is she will chase rabbits that are in our backyard. This is something that concerns me. First, I don't want her harming the rabbits, as our other dogs and the bunnies have coexisted in the backyard very well for over a year. Secondly, will she know the difference between small animals and my chi, or will she see him as another small animal/prey? Clearly, I am no animal expert.

My chi is accustom to freely roaming the house but due to the uncertainty of Bella's behavior, we are keeping the dogs separated in different bedrooms unless we are with the them. I have also resorted to keeping one or both on a leash, inside the house, when we let them out of the bedrooms at the same time. I know this is not the right thing to do nor a good way for dogs to live, but I feel I can quickly control anything that may happen with that leash control. However, this is becoming very stressful for me and I am sure the dogs are picking up on my anxiety.

Does anyone have any thoughts or experience with regards to this? If she was going to "attack" him, what would the warning signs be? There are times she looks sideways at him, which gets me nervous. Is that a sign of aggression?

TIA

First off, welcome to the forum :) Yay for adopting a shelter dog too :)

Keeping them seperated unless you're there to supervise is good. You don't know this dog yet, so should always be present during interaction until you can trust them together. Sounds like you seperate them in different rooms too, rather than by crating, which sounds good :)

All of the following is my opinion.

The paw on your chi as he's passing sounds like wanting to play, to me, but I don't know about the lunging. I know some dogs nose-butt to say play with me. She is just a pup though, but her breeds are herders, so it would be instinct to chase.
Does she ever stand over him, body stiffened? Anything you see as a sign she's getting a bit tense, stop her. A firm touch, just to distract, and a NO. If you can't distract, take her out of the room until she's calmed down.

I agree about not letting her chase the rabbits. It would be too easy to mistake your chi for one in the midst of a persuit. For now, I'd only take her out on a leash, or at least supervise while she's outside, and watch for any signs she's gonna chase them, and stop her first!

Thank you for your response. It educated me about the paw extension as she does that to us humans also. Therefore it makes sense.

To answer your question, we have not allowed her the chance to stand over him. When she does lunge, her ears are perked up straight and tail curled up. I haven't notice if she is rigid or stiff but I will keep an eye out for that. We pull her away too quickly. A few minutes ago I got the dogs in the same room, both leashed, in order to allow Bella the chance to smell my chi but my chi began to growl so I stopped that interaction. Not sure if that was the correct thing to do or not. I was concern that growling could get Bella upset.

She did get to know the other dog in our house, who is a pug. The pug has a completely different personality...very old, docile and inactive. Bella had her ears up and was just trying to smell her behind her ears. She also appeared to want to play by trying to touch her with the paw. Pugsley is first 20-25 lbs...much bigger than my chi. Secondly, isn't a playfull dog so she just walked away.

Thank you for your feedback. Please keep it coming.

I actually would treat Bella as the newcomer and puppy. And she would be the dog that would be on leash or confined. I would allow the chi to have her regular house and freedom.

I would think that daily training sessions with Bella and the chi. I would do everything to support the role of the chi in the house. Treat the chi first, feed the chi first, let the chi go through doors first, the chi gets to sit closest to you. When Bella tries to act up towards the chi correct her with a strong "uh uh" and then tell her to leave it. And reward her when she is being calm around the chi.

You can also use a lead and tether Bella in the same room with you and the chi.

Basically just keep reinforcing that the behavior Bella has to show to the chi that you find acceptable is being calm around him.

I don't think the puppy means any harm. But due to the size difference, I agree with you it isn't something to be casual about.

It also might help to take Bella and really work her out . . . running and chasing . . . etc and then having her around the chi and work on the training of being calm.

Good luck.

An ACD/blue heeler mix will be very high energy, so even though he's on his best behaviour now and seems low-energy, that may change! It's important this dog gets vigorous exercise, or else he'll become destructive and could play too hard with your chi. The only time my one dog, Kye, chewed anything of mine was when I had surgery and couldn't get out to run her like I usually would. Mine are also an active herding breed, and they're mixes as well.

The lunging could be a playing thing, I watch my two pups bound up to eachother all the time. I can't see myself what yours is doing so I couldn't say for sure.
