Peggy, I didn’t address your question regarding weight loss. You need to feed less to cause weight loss. You will have to include the calories in any treats you feed in the daily intake. There is a calculator on this site to give you an idea of how much to feed. You should base the amount to feed on the ideal weight.
When trying to feed for allergies, you must make sure everything you feed, including canned food and treats are the same protein as the food you feed. You also need to make sure there are no grains in the treats. This is basically an elimination diet. Most of the time this method works. If that doesn’t work, you may have to consider intradermal testing.
