Frequently Asked Questions
How much food does my dog need per day?
As a rule of thumb, about 2-3% of body weight at normal activity, adjusted for age, breed and activity level.
Does an active dog need more food?
Yes, highly active dogs (e.g. working or sport dogs) have a noticeably higher calorie need than calm indoor dogs.
How often should I feed my dog?
Adult dogs usually 1-2 times a day; puppies more often with smaller portions spread through the day.
How do I tell if my dog is overweight?
From above, you should see a slight waist, and the ribs should be easy to feel but not visible – when in doubt, a vet can check.
