Hello how may I help you? I'm curious about how much dog food I should go through in a week Sure, I can help with that. Can you tell me what kind of dog you have? Pug Great. With a dog like a pug you should be feeding about 1 cup a day. Little guy eats 5 lbs a week That seems like a lot. You may want to double check with your vet to make sure he's at a healthy weight You he is chunky It sounds like he might need a reduction in food. And maybe some extra walks! Ok i will follow through Good luck with your dog. Give him some pets from me!
