fuzzy eating

Question
I have 2 spayed 6 months old Yochon's(Yorkie/Bischon).  I have tried all kinds of dog food but they don't like anything I have given them. I buy the best of dog foods dry and can(I mix a little can w/dry)and they just swell it and walk away.  It can sit all day and they will not eat it, no matter what. I do throw out the old food and feed them again in the evening. Sometimes later on in the evening they finally eat it. I am just afraid that they are not getting enough nutrition. What can I do to make their meals better?

Answer
What does the vet say?  In nearly all cases, the dog is either sick, or over fed if it won't eat.  You seldom see a healthy dog not eating all it needs unless it has been rehomed or somthing.  

Your dog definitely should be narrower at the waist than the hips and chest.
You should be able to easily feel the ribs, but not see them.  Each dog is
different.  Standard recommendations are a good place to start, but each dog
must have its food adjusted to its individual needs. Here is a link to a good illustrated guide,

The worst thing you can do is to bribe a dog with rich foods into eating more than it needs. Instead, Put down the dish with what the dog should eat, and give it 15 minutes to eat. Then take it up. Do not give it anything to eat until its next scheduled meal. In a few days, it should be eating what it needs. Continue to check its ribs and adjust the food as needed. This is not easy. I had a Shepherd go 3 days on a few nibbles. I was a wreck, but she was fine. It is almost unknown for a healthy dog not to eat what it needs. Unfortunately, in too many cases, it is less than the package says, and less than the owner thinks the dog should have. Many dogs are quite good at holding out for tastier chow. Like kids, sometimes it calls for tough love.
