(Quick Answer) If I Feed My Dog Human Food, Will They Not Want Their Kibble Anymore?

It depends.

If you would like to provide human food (please double check with your veterinarian) to your dog, this can be a great rare treat. More importantly however, providing human food or any kind of high value treat can and should be used in scenarios where your dog has a more difficult time making good decisions.

For example, when you're walking past a dog park if your dog feels very excited and distracted you can use a high value treat as a reward when they're able to give you more of their attention.
