How do I keep my 2 female dogs from fighting with each other?

We adopted a border collie around Christmas, she was pregnant & had 6 puppies (we kept 1 male). The girls have always been a little jealous of the attention the other gets, but we never had any problems until we went on vacation 2 weeks ago when the girls got in 2 fights where one had to go to the vet. We got home and they got into it again & the border lost a tooth. My beagle had been the alpha by default before I got the border, I had 2 greys at the time and neither of them wanted to be alpha. The border has a more dominant personality, but the beagle doesn't want to give up her throne. We've made sure to always treat the border as the alpha, always taking her out first, petting her first, giving her treats first, etc. They're separated now, but that's not a long term solution. I started giving them anxiety droplets, they seem more calm, but I still haven't put them in the same room together. Am I going to have to take them to a behavioral specialist? Any other ideas?I've taken the beagle and the puppy to the dog park to let off some of their energy. Am I okay to take my border there too, or will she start fights with dogs there? I'm not sure if it's safe to take her there, but she needs exercise too & I live in a condo where the dogs can't be unleashed.Oh yeah, both dogs are spayed. The border is usually the calm quiet one, which makes me wonder what's going on.The beagle doesn't have a dominant personality, and can barely defend herself against the border. That's why we've tried to show the border as alpha, because she's definitely more dominant.I also try submitting both dogs every day - just hold them down until they submit to me. They both see ME as the alpha, but I'm still not a dog and they know that & they're fighting for MY attention. I feel bad...

I think you do have a dominance battle going on and you might not be able to resolve it. I would definitely work with the behaviorist and see if you can make some headway since these two dogs have lived together for awhile. I'd also get the border spayed and the beagle too if she is not. But if you can't resolve it and you can't keep them apart, finding another home for one of them may be in their best interest.Hard to know if the border would cause problems at the dog park. If she generally gets along with other dogs except for the beagle, it may be fine in a neutral social situation. If she is generally dog aggressive, then it's a bad idea and frankly you'll have problems solving it in your own home as well. Take her on a leash first and see how she acts.

Canine are pack animals and an order has to be established, but can be managed. If your beagle is the dominant female, do not take out the border as first dog. Reverse your decision . Any overdoing of favoritism is not good, in my experience. The original alpha female is defending her ranking so we must try and get the border to accept, rather then challenge. Socialize them on walks together and make it known to them that they are a team. A dog's age has some to do with how they all interact. There will be a point in time when they will accept each other, but it takes work, patience, and remember, that no matter what you do, sometimes it doesn't always work. Good luck and take care.. Sometimes spaying will help....

This is going to sound mean, but use a shock collar... every time the border gets aggressive zap her. It won’t take long for her to learn to be nice.We had a pair of Beagles that loved to run deer and nothing we did would stop them until we gave the "Training Collar" a try. Them two beagles ended up being two of the best rabbit dogs in the county. If they even smelled a deer after that, they turn around and head in the opposite direction.The thing about a training collar is; they don't know where it's coming from, so she wont know it's you and she wont know it's not the beagle - all she'll understand is when she gets mean it hurts.

although it is obvious that you have a domination battle the big question is where are you in this band for it seems each dog is trying to be the alpha surly that position should be you. you should watch them and intervene way before a fight brakes out you controlling them not the other way around as an alpha would not let a fight go that far. if you are the alpha and give control to the pack then try controlling both dogs where they go, and what they do, how they do. this way the jostling hopefully will decrease as you are in charge not he dogs. yes if you do find this hard to do it might be best if you find a behaviorist to help you good luck
