What happens if a 3-month-old dog overeats?

A three-month-old dog that eats too much may develop indigestion and stomach discomfort. Because a puppy’s digestive system is not yet mature and cannot handle excess food, sugar, or fat, overeating can cause diarrhea, vomiting, or belly pain. In addition, eating too much may lead to obesity, too-fast growth, and other health issues. Therefore, feed the dog on a fixed schedule and in set amounts, and avoid too many treats and human foods. If your dog has overeaten, give a little warm water and let it rest quietly to help digestion and elimination.
