There is some debate around this, but in general, most experts recommend feeding dogs two meals a day for adult dogs. Some of the benefits of two meals versus three meals include:
• It mimics the natural feeding schedule of dogs in the wild. Wild dogs and wolves typically eat one major meal in the evening after a hunt, and sometimes small snacks during the day. Two meals a day provides a more natural feeding cycle for domestic dogs.
• It prevents obesity. Feeding fewer, larger meals tends to be more satisfying for dogs and prevents them from frequently begging for food or treats. This can help keep calories in check and prevent obesity.
• It allows a more settled digestive cycle. With two larger meals, a dog's digestive system can rest for a longer period between meals. This may be easier on their stomach and GI tract.
• It simplifies the feeding routine. Two meals are simpler for most owners to manage versus coordinating three meals a day.
However, some dogs may do better on three smaller meals, especially younger puppies, toy breed dogs, and dogs with certain medical conditions. Some potential benefits of three meals include:
• For puppies, more frequent meals help support growth. Puppies need more calories and may not be able to eat enough in just two sittings.
• For toy breeds, smaller tummy sizes mean they can only eat a little at a time. Three small meals prevent them from going too long without food.
• For dogs with conditions like diabetes, pancreatitis or gastrointestinal disease, three meals may be easier to manage and prevent drops or spikes in blood sugar.
In the end, you know your dog best. If your dog seems very hungry, has low energy, or is not maintaining a good weight on two meals a day, talk to your vet about switching to three smaller meals. But for most average adult dogs, two meals a day is a great place to start.
