A dog’s personality and temperament should be checked to adoption.
With an older dog, you usually know what you’re getting.
I would not recommend a dog or cat unsupervised around infants and small children.
When my son was born, we invited our landlords to visit our new baby. Our cat positioned herself by his bedroom door and hissed and growled at the landlords when they tried to enter his room. She thought the baby was her baby.
