Sherlock will be 3 years old in February 2022. He is a neutered male. He was purchased as a pup to be a livestock guardian dog. He is current on his vaccinations. Very shy, but not aggressive to people. I don't know how he is children or other dogs, I wouldn't trust him with cats. He is a good guard dog, he barks when needed. He cannot be a livestock guardian dog as he kills sheep.
