I don't think it is an issue of GSDs not "liking kids" - it is an issue of so many poorly bred, nervy, insecure GSDs out there who are not 100% sound and having temperament issues! It is being willing and able to find a scrupulously honest, experienced breeder and being willing to wait and pay for the right GSD.
I had a lady call several years ago. She had a baby and wanted a GSD.....a working line GSD specifically, she had 'done her research' and wanted a good mentally and physically sound dog. Both she and her husband had had big dogs as children, and her husband particularly wanted a GSD again. She is an attorney, her husband a teacher, and she works in her mother in law's law firm. Lives on a couple acres in the country......many many pluses for a good home
I told her I did not breed often, that I had produced this kind of dog and even then, I was hesitant to place a puppy in a household with an infant. But that if she was willing to wait I would work with her. We spent quite a lot of time talking.
I had the L litter, only 2 puppies and I told her with only 2, it was unlikely either pup was going to be the right pup for her, I offered to help her find a pup elsewhere, but she wanted to wait. The L's were very intense and high drive - one went to a SAR handler and I have the other.....not pups that would have been easy with small children because of drive and intensity. They like kids, but full time with an inexperienced owner??? Still not the best match as it stands. But in the right homes. When the Ms were born, I had 7 females and knew from others having pups from the sire, that I would have lower drive, less intense pups in the litter.
Morgen has been a joy with the 3 year old from the start.....never mouthy, intensely bonded. Maddie would sit in the big dog bolster bed reading to the puppy until they both would fall asleep - no toys all over the house either because the puppy was now a full time occupation for the baby, which Mom said was a plus....this was a good child with the puppy - was taught to respect the puppy and be gentle. It works both ways.
What the buyer did NOT tell me, at the time of me delivering the puppy and a subsequent visit or two to check on things, was that she was having a second baby.....at last contact, Morgen is great with both the 8 month old and the nearly 4 year old and is inseparable from the kids....the ideal companion/protector dog that the buyer envisioned.
Morgen (GSD) with Maddie ~ about 5?6? months old
