Can you mix commercial raw dog food with raw meat from the supermarket?

Most healthy dogs will be able to tolerate raw meat from the supermarket very well. However, you should be aware that food sold for human consumption is sold with the assumption that it’s going to be cooked, so it doesn’t undergo the strict bacterial testing that raw pet food does. This does mean that there is a higher risk of bacterial contamination so you should be extra careful about hygiene, and take especial care if you have a young puppy, a very elderly dog or one with an underlying health issue. 

We would recommend popping any meat from the supermarket or butcher into the freezer for a few days before giving it to your dog – both to inhibit any bacterial growth while it’s being stored, and to kill any parasites that may be present.
