Hello how may I help you? Do you give pet advice? I do give pet advice! What kind of dog do you need advice about? How did you know I have a dog? I'm sorry for assuming. What kind of pet do you have? A golden retriever and I want to know how much dog food should I buy for one week. He's a big dog. Great. How many times a day do you feed your golden retriever? 2-3 times a day Thank you. I believe that for a golden retriever eating the recommended amounts 2-3 times a day that 20 pounds of dry dog food a week should be sufficient. Oh okay thats great info to know. I don't want to be overspending on my dog. Thanks for the help. You're welcome. Have a great day!
