New findings from the Dog Aging Project suggest that feeding adult dogs just once a day might come with some real health perks. But it’s not a one-size-fits-all solution—and it’s definitely not right for every dog.
Why Some Experts Are Recommending One Meal a Day
The study looked at data from more than 24,000 dogs. It found that those fed once daily were less likely to develop a number of health problems—things like dental disease, joint issues, and kidney or liver troubles. These dogs also performed better on cognitive tests, which may point to benefits for brain health as they age.
This isn’t completely surprising. In both humans and lab animals, intermittent fasting has been tied to better health outcomes. The idea is that fewer meals might help prevent overeating and give the digestive system more time to rest and repair. Some researchers even think this eating pattern reflects how dogs’ wild ancestors, like wolves, ate—big meals, but not every day.
When Once a Day Might Not Be the Right Call
Still, just because some dogs seem to do well on one meal a day doesn’t mean it’s the best approach for every pup. This study was observational, meaning it can show a link, but not prove that one meal a day causes better health.
Here are a few reasons why you might want to stick with multiple meals:
- Puppies need to eat more often to support their growth and energy needs. Skipping meals could lead to low blood sugar.
- Small dogs may need at least two meals a day to avoid vomiting bile from an empty stomach.
- Dogs at risk of bloat, especially large or deep-chested breeds, might be better off eating smaller, more frequent meals.
- Medical conditions like diabetes or GI issues often require more regular feeding schedules.
The takeaway? While once-daily feeding may be worth considering for healthy adult dogs, it’s not a decision to make lightly. Talk to your vet before switching things up—your dog’s age, breed, size, and overall health should guide the choice.
