“It’s important to never completely trust any size dog alone with a baby or small child.”
So TRUE!
+1000.
We have a Shepherd/Rott mix, a 90 pound bundle of love. She's knocked over my grandson on many occasions, while we were rough housing. He's gotten used to it (he'll turn 8 in a couple of months), and his other grandparents have two larger dogs themselves.
Even when I play with the dog, there are times I get wary. It wouldn't take much for her to take a nip out of me, though she reacts appropriately on the few occasions where she gets me on the arm or hand.
There is no way I'd ever let her near an infant or toddler, she's just too big for a small child.
