Dogs and babies

Chloe

So we have a special needs chihuahua ( her cerebellum didn’t develop so she has balance issues ) and her and the baby love each other, but she can’t get up and get away from him when he’s being mean and pulling her tail /legs. I keep trying to to teach Archer “gentle” and saying no. I’m scared that one day she’s going to get scared and snap at him.

Any suggestions?
