What age do you have to be to adopt a dog?

Woof woof? do you mean for the Dog or the prospective owner? It really is a serious matter that should be given more consideration. Kids frequently swap items with no concern as to their long-term maintenance, llike tops and other toys- not applicable to a living pet. also there is in a sense a minimum age where the animal can live on its own and is weaned from its mother- with Cats usually this is about 8 weeks- and they have the semblance of a lithe, adult-like body but still kittens- with puppies it would vary according to the breed. It is by no means as tightly regulated as automobile and gun licenses, but there are allied problems from the maturity standpoint. an Excellent question, Ruff!
