What happens if a dog eats too little dog food?

Dog food is nutritionally complete; if the dog eats little, the owner can offer other rich foods for balanced nutrition without harming health. But if it rarely eats kibble and the owner feeds only single foods long-term, it becomes malnourished, affecting development, causing thinness, low immunity, rough dull coat and easy infection.

Therefore, even if the dog prefers other foods, ensure its overall diet stays balanced and complete.
