Here are my two gaurd dogs gaurding the house...both of them Doberman pintchers. The left one did not have his ears cropped. I adopted them from the local shelters and that is the only way to go...saves money and most of the time you don't have train them as much. Especially house training them....The red Doberman is a puppy still and sometimes a handful, very powerful. These dogs are very loyal and smart. They hear everything going on even outside and they will let you know...I like that because I'm a bit hard of hearing and they let me know if someone pulls into the driveway or is walking outside...Especially the ups or mail person....and others.....Enjoy the picture.
