Hi, everyone. As some of you may have seen, we found a puppy on the side of the road on 1/15. We have since located her owner, but only to find out she doesn't want her. She said we could keep her, or she would ind her a new home. She is 6 months old and an Argentine Dogo/Jagdterrier mix. So, basically a large game hunting dog. I originally thought german wirehaired pointer/pit bull...boy was I off!! Anyway, we also have a 7 year old chihuahua mix and a 11 year old yellow lab mix. At times, they get along like angels, other times they want to kill each other. Last week, our chihuahua bit her on the face in the kitchen over a piece of food on the floor. They ended up fighting, and we had to pull them apart. Just today, they were all following me around the kitchen while I was making eggs. I admit, I used to throw Sugar and Sabrina a few pieces before we got Ellie. I was going to put up the spatula and move them to the other room when I saw Ellie (puppy) growl at Sugar (lab). I yelled HEY, and in a moment Sugar was biting her face. Soon Sabrina joined in and we had to pull them all apart. Keep in mind, Sugar is an extremely submissive dog, and I never believed she would actually attack another dog. Also, Ellie likes to lick Sugar and jump all over her when she is trying to sleep. She is starting to growl at her, just to tell her to back off, which I think is fine. Sabrina will NOT tolerate any type of play or too much sniffing. I HATE it when they fight, and I hate worrying about it. Sugar and Sabrina haven't gotten in 1 fight in the 7 years that they have been together. Is there a way to fix this, or should we return her home before she becomes too much a part of the family? They need to be able to stay together peacefully when we aren't home, but I don't know if it's possible. Would getting Ellie spayed help? We don't want to set an appointment before we know if we can keep her or not. Help please!
