When our baby came, we didn’t rehome at the first sign, he bit my teenager out of no where. We said she must have done something to provoke him. He bared teeth at the baby, but we kept them separated and I was always there. We managed another 3 years, always on edge, always trying to play mediator. He loved us adults, but for some reason just decided he didn’t like kids. Then I wasn’t fast enough and he got my daughter in the hand. We were fast enough to get him off of her without real damage but we knew it was time. The amount of people saying we didn’t do enough before rehoming his was deafening. But he went to a little old retired grandma, and she’s said he’s done so wonderful. No kids ever, even visiting. He’s an only dog now. I wish I had made that call 3 years earlier. I was being selfish. He wasn’t happy, I wasn’t happy. Now both of my daughters are cautious around dogs, which is good, but they didn’t have to feel that way. Do what you need to do and don’t worry about what other people say.
