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. However, as mentioned above, pressure canners are very large and heavy to handle, and bulky to store.
Keep the water boiling. Process the jars in a boiling-water bath for 40 minutes for pints and 45 minutes for quarts. Remember to adjust the time if you are at a different altitude other than sea level! Pressure canners work better for tomatoes and other low acid foods - you'll get less spoilage with a pressure canner.
