Could she be jealous? Here's the deal:
I've had my dog, a female schnauzer/ chihuahua mix, for 3 years. I just recently, about 3 weeks ago, got two female dachsaund puppies. My older dog never before had any aggressive characteristics about her. She has always been very nice, gentle, and caring towards other dogs. In fact, I have 3 other dogs as well, however, these other dogs are all male and she never had any problems with them. For the most part she is an outside dog. We keep her out during the day and in during night time. Lately, since we've gotten the puppies, she has been digging out of her fenced in area and coming to the door wanting in. She has been aggressive towards them and even in one case bit one of them. She also has been being very aggressive towards one of the male dogs as well. I think she's jealous of them so I've been keeping her in the house during the day as well so that her feelings will not be hurt and she will not dig out and something bad happen. I also think that since she was raised around only male dogs she might be especially jealous that there are two other female dogs around. Unfortunately, I don't know if that is logical.
Does anyone know anything about this type of behavior? |
