Quoting Mommy Meyer:" That is a good suggestion to adopt an older dog. One of mine is a rescue and he is great. The only thing ... [snip!] ... bed so now he uses that instead of trying to get on the couch. An older dog will have less energy which could be beneficial. "
Plus you can tell alot more about the dogs temperment and personality once they get a little older. Some dogs just dont have the temperment to deal with toddlers, even if they are raised together. I have seen it happen to a couple friends of mine. They get a dog, and the dog ends up snapping at or biting the babies, and suddenly the dog has to go. I specificly looked for a dog who was going to be good at handling young kids and had experience with it. My son is now 15 months, and she adores him, even when he pulls her ears lol. Plus IMO rescued dogs know they were recued, and can become some of the best family dogs.
