Should I fear for my grandchildren, or was this just a doggy spat?
We have a Shih-Tzu/Pomeranian cross who is about 6 years old. My son adopted a Basenji last year who is roughly 3 years old. They have had a few visits, mostly at my house, in which the Basenji, who is female, has been kept on a leash. This past weekend, however, she was left off the leash and, in less than an hour of being in the house, she attacked our Shih-Tzu cross, who is about half her size, grabbing onto his scruff and part of one year before locking her jaw and refusing to let go. (Yes, I know there are those who will tell me that "locking the jaw" isn't a really good term for it, but my husband and son, driving fingers where the jaws are attached at the back of the mouth, weren't able to break her loose until one of them also twisted the collar, choking her until she was forced to either let go or stop breathing entirely.) I'm a little worried about a repeat performance if we ever let them bring her back over, but with the speed she did this, I'm also worried for my grandkids, the youngest of whom is only 3. For anyone who works with a vet, might this be a one-time-thing that the Basenji did just for dominance, or should we worry about her attacking one of the children?
