The most common “issue” that Dobermann owners have, when a new baby arrives in the family is that the formerly loyal-to-the-parents dog will abandon them and station itself in the nursery to ‘guard’ the new baby.
If I’d been able to have kids, they would have grown up with Dobermanns.
When I was a kid we got a Boxer who was about 1 year old at the time. My mother’s cousin was a breeder and showed them and later got an absolutely beautiful Doberman who went to Westminster. The boxer came to us because he was returned by the guy who bought him and had to give him up because IIRC, he had to move because a new job and couldn’t take him with him. Boomer was an amazing dog; very bright and loving and playful but very serious and intense when it came to protecting his “family”, but he loved kids.
One time a friend of my father’s came to dinner at our house with his wife and their infant daughter. Boomer was fascinated by the baby but was very gentle and wouldn’t even get too close to her as if he knew he might scare her. But when her mom laid her down on my parent’s bed for a nap, Boomer stood guard, wouldn’t leave her side. When my mom and the baby’s mom when to check on the baby she had managed to roll past one of the pillows and had started to roll toward the edge of the bed, and there was Boomer, gently nuzzling her back toward the middle of the bed. When my mom and the baby’s mother came into the room, Boomer was wagging his little stumpy tail as if to say “I did good – right?”
