Routines ensure a dog eats on a schedule that supports their metabolism and healthy digestion. A daily schedule also helps with potty training and keeps a dog “regular.” Plus, daily physical activity and playtime support a dog’s physical health. In terms of mental and emotional health, a repeatable schedule lends a sense of security from knowing what to expect. If you leave the home, your dog knows you’ll return. If the food bowl is empty, the dog knows more food will be in the bowl at a certain time of day.
