My 5-year-old fixed female boxer mix is not generally an aggressive dog. She has never actually bitten a person, dog, or cat (not even when she is rough-housing–and my cat completely bosses her around). My boyfriend has 3 other dogs, and all 4 dogs spend time together, although we live separately. His fixed 7-year-old female Dachshund will occasionally growl at my dog if my dog gets near her when she is cuddling with either of us. My dog always wants to butt in between. There have also been about 3 growl and bark issues between them (in two years). Generally it’s been a non-issue, especially when we aren’t around.
We left all 4 dogs outside (within the underground fence) when we went shopping. We returned to find his female seriously injured with multiple bite marks. Thankfully, she has recovered (after a 3 day vet hospital stay).
My question is–could it have been my dog that attacked her? The other dogs are either too small or too big to have inflicted the damage. That leaves
A. My dog
B. A coyote
C. Another dog that wandered onto the property.
The house is in a nice subdivision, but the property backs up to two farms. The back farm is separated partially by a barbed wire fence and partially by a wire fence–and much undergrowth.
My boyfriend does keep food and water outside. He doesn’t think any animal would risk the 4 dogs to get to it. (They are mostly indoor dogs, but the food is inside of their large dog house.)
The dachshund was about 10 feet from the property line when we found her. Her wounds were only on her back portion (hips, butt, and stomach). The vet said they were bite and pull (lift) wounds. She had released her anal glands.
My dog didn’t have any defensive wounds on her. She didn’t act at all guilty after this (usually if she does something she knows she shouldn’t, she hides). Could she have done this?
My boyfriend initially thought my dog was a likely candidate. Neighbors have suggested coyotes. There was a pretty serious coyote on dog attack in a subdivision a miles away, but that was two years ago.
