Hi sorry again for the no pics.. I have had some health issues I am trying to get under control. Mean while I have broke down and bought royal canine dog food. I bought shampoo for yorkies.. but after I started using it hestarted being itchy.. he had licked and itched his hair off the top part of his front legs.. and his hair is dull. Woo do u think the change in dog food will help and getting rid of the shampoo. Not sure what to use on him. And suggestions?
