Hello how may I help you? I need some help with my dog. What kind of dog do you have? It is a chihuahua. Great! What's the problem I would like to know how much dog food I should typically go through in one week? She weighs about 10 lbs and I'm scared I'm overfeeding. Great question. You should be feeding her about 1 cup of food a day. How much are you feeding her now? 10 cups. I knew it was too much! Oh dear, yes, that's too much. She's going to need to be put on a diet. I will reduce the amount right away. We will go on extra walks daily as wel. well* That was going to be my next advice. Lots of walking! Anything else I can help with? Thank you so much. That was it! You have been very helpful.
