Why is my active pug puppy always hungry? Should I feed more?

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. I would continue to feed her the small breed puppy food at the recommended amount on the bag. Puppy food is calorie-dense, so as to meet the energy needs of high-energy puppies. You can try breaking the amount into smaller, more frequent meals (ie three or four times a day) so she feels like she is getting to eat more. I would not over-feed her for fear of early onset obesity, which can lead to significant health issues later in life. You can also supplement her diet with healthy treats during the day such as carrots or green beans. After she is spayed, her energy requirements will decrease and she will need to be fed less food so she doesn't become overweight. I hope this is helpful!
