Legal Issues. Many states have laws in place that prevent the sale of puppies younger than 6 weeks old. There are 17 states that require a pup to be at least 8 weeks of age before you adopt him out and one state that specifies pups be at least 7 weeks of age, according to the Michigan State University Animal Legal & Historical Center.
If you like the idea of pressure cooking AND canning, you can have the best of both worlds by buying a pressure cooker/canner (with pressure gauge) and using it for canning, as well as to pressure cook your meals.
