Agressive Female Jack Russell
So I have 3 dogs. A 8 year old male Jack Russell/Chinese Crested mix, a 2 1/2 year old female Jack Russell terrier and a 10 month old German Shepherd. My small 2 are fixed but the German shepherd is not. We had my first dog by himself till he was about 5 and then we adopted my female jack and she was about 4 months when we got her. They went through getting used to each other and we playing within a couple of months and get along fine. She is submissive to him. We moved into a new house and about after a year in the house we wanted another dog and have been wanting a German shepherd for at least as long as my husband and I have been together about 8 years. We found a breeder that lived a few miles from our house and she let us bring out dog out there to see how they would interact. She also breeds jack Russell's. While my older dog was happy and trying to play with puppies my female would try and charge them so she told us that we could get a female because my jack is already an alpha and it would be constant fighting if we did so we got a male German shepherd.
I expected it would take a little time for them to get used to each other but the males get along fine and play and there isn't really an aggression from the older male to the younger male sometimes my older one will growl a little and we tell the younger one he doesn't want to play and then we will play with him. My female hasn't gotten used to him at all. She will get in a mood and if he walks by she will charge him and he will put his face on the carpet and she will bite one his nose and we will then call her name and she will run and hide.
We have tried time outs and it seems like everything but she still does this towards him and we have had him for about 8 months now. My older male whet through training classes and passed all 3. We took my female and the first week we learned sit and she didn't sit until the last week of the class and she doesn't come when called.She was very difficult to train and the only trick she does is sit and its not all the time. Every time she is in a harness she will escape and this one is bad because she did this outside the vets office close to a street and every time my husband went toward her she would back up closer to the street and I walked towards her and then got down to her level and was able to get her before anything bad happened. I think that while the 2 boys listen to us i don't think that my female sees us as pack leaders and she really has no respect for us. We love all 3 of our dogs but I want the younger 2 to have a better relationship.
