Q: My black Lab, about three years old, is very aggressive. While perfectly friendly once she knows you, she will nip strangers’ heels. But my bigger problem is that several times now, she has jumped on a smaller terrier who lives next door, actually biting that dog badly enough that it had to be taken to the vet to clean its wounds and perhaps get stitches. The last time it happened, my neighbor had the gun out and demands that I get rid of my dog or he will kill her. Unfortunately, I have never been around when all this happens. I should note that my dog is afraid of thunder and firecrackers and that this is the only dog she has ever bothered. I am in my 80s and live alone. I do not want to lose my pet. If you could help with suggestions, it would be very much appreciated.
