You may think your dog wants or needs variety. The truth is – even if your dog won't eat their food but will eat treats – they will happily eat the same food every day their entire life. It's up to you to make sure you provide a tasty, nutritious meal. Your dog is always hungry because your dog descended from opportunistic hunters who were accustomed to eating what they could get when they could get it. If you've ever wondered, "Why is my dog suddenly hungry all the time?" this could be the reason.

The cause. Frequently, the cause of a dog's pickiness isn’t a result of its behavior. It’s usually the result of humans feeding table scraps or too many treats. Not only does this increase the risk of obesity, but it also can encourage "picky eater" dog food behavior. Your dog avoids eating in hope of getting more exciting food than what’s in the bowl. The best approach is to stop feeding your dog from the table and limit the number of treats. Remember that dogs and cats have different nutritional needs than we do, so what we eat isn't necessarily balanced for them, and certainly not the best dog food for picky eaters.

When your dog was younger, if you tried offering several different foods to determine the right fit, you may have encouraged your dog to hold out for something better. If you’re opening multiple cans of food and trying to coax your dog into eating something every meal, then your dog has you trained.
