Our first dog is Jedi, a mixed breed. She was like our experiment because we didn't know about dogs then. But we loved her such that she was sleeping in our bedroom. Her favorite breakfast is hotdogs, roasted in the oven toaster otherwise she wouldn't it. But when a dog breeder learned of it, we were cautioned against giving processed food to our dogs - hotdogs, spam, corned beef, sausages, and other canned meat. But since Jedi loved hotdogs, we were so stubborn.
When Jedi died of renal failure, that was the time we realized that processed food has a bad effect on the kidneys of the dog. Now we have a policy against processed food for dogs because we care for their kidneys.
