answered question 10/5/2009 How Often Should I Feed A 3 Month Old Yorkie Poo Puppy. I Was Feeding 3 Times A Day But She Seems To Only Eat Two Out Of The Three Meals I Give Her Lately? Well I have a dog myself. I feed it three times a day and if it doesn't eat it in 15mins then take it away. If they still don't learn then bring them to the vet about food.
