My DD bought a Rott pup. He is 14 weeks old. Her and her fiance have broken up (another story) We have 4 dogs that are good with our animals. I love rotties but do not know how they will do with goats and chickens. He will not ever be allowed around them unsupervised or off leash. At what age would he be able to be trusted with them? How do we train him to be trusted? I am just worried he will hurt them. If he does he will be gone. Thanks
