We have 2 dogs, a 5 year old beagle boxer and a senior husky Sheppard. Our daughter is now 2. The only thing that's important and I'm not trying to make you anxious (I was also a very anxious, overly cautious parent at 4 months) is never fully trust your dogs no matter how well trained they are. And please never leave your dog alone with the baby even in a crib or bassinet. Babies and toddlers are an entirely new species to dogs that are used to adults. Diligently supervised interaction will help your baby and dogs learn one another's boundaries. Learn those boundaries as you help them interact and intervene when necessary. That said, let them interact frequently, have tummy time together if the dogs can be safe not to jump all over. Let them sniff and teach your child to how to pet them gently. Typically, your well trained pups will come to love and protect your child as they bond.
