The Vet seems to think he may have some of that in his motley mix. He did go after the neighbor Westie type dog once. My sister's lab is afraid of him.My uncle Anthony had a Maine coon tomcat name Louis who was 36 lb.
Louis killed the neighbor's poodle when it dug under the fence and got into his yard.
Well I warned them that Louis was very territorial, and liked French food.
mitzi said nipped!I had a dog that was part cattle dog, part beagle. A beagle got to the Mom . A co-worker gave us a puppy. We sure didn't consider them designer dogs because they were 2 breeds. She was a good little dog except when her instinct kicked in and she tried to "herd" you and nipped at your ankles.
