feeding a poodle

Question
my friend mixes dry food with tuna for her toy poodle - 7 mths - Is this okay?

Answer
NO!  Unlike the dog chow, tuna is not the complete and balanced diet a dog needs.  If she has to do it to get the dog to eat, likely it is over fed, over weight, and won't live as long.  Check http://www.puppychow.com/products/popup_body_condition.aspx
