My husband, 3 kids, and I went to the Humane Society to adopt a dog. We found one that we like and she is a lab mix that is 4 1/2 years old. She is sweet but is pretty strong. Everyone loved her but my concern is that she has not "grown" up with us if that makes any sense. I'm wondering if she would be nearly as protective over us as a dog would if they were with us since they were a puppy. I don't know if that makes any sense or not, but I'm just a little uneasy. The dog really is sweet, but I am just a little uneasy about the age since she has had 4 years without my kids around. She did great around them and everything. Any advice on this?
