Hello how may I help you? I have a question related to my dog. Yes. I can with questions related to your dog. How much dog food should I use in a week? What size of dog and breed do you have? I have a golden retriever, about 50 pounds. Recommendations for Golden Retrievers weighing 50 lbs are 10-15 lbs a week. Ok, thank you. You are welcome. Anything else? Nope, that's all! Great. Have a nice day.
