I agree with the rest. Ive got a black lab and she is the most gentle dog i could think about, being around all other animals. Doesnt matter, shes great with the chickens, rabbits, kittens, dogs, people. All living things. But she is an excellent LSG and she is very alert with a deep loud and intimidating bark. Some might say she barks "too much". But anyways, it really depends on the individual dogs temperament. Some are just born with motherly instincts and other have higher prey drives. You can also get some good training into puppies with the right instincts and they will be excellent LSG's for you. Maybe look into a trial period? And check out the puppies natural inclinations. Good Luck!!!
