In response to Baby Girl Yorkie, P.J. has food available to him all the time. I give him the Nutrical at bedtime so his blood sugar level will not drop during the night. He really looks forward to it. His ears will perk up then.

I also send the Nutrical to the groomers because I know that he really isn't going to eat and drink properly while he is there.
Thank you MM yorkies for the cottage cheese/yogurt advice. I think I will try that and see how he does with it. Has it caused any intestinal upset in your babies?
Like June Bug stated, I also wondered if this visit was a little stressful on him. My hubby accidentally took him to a different groomer. She did a good job, but maybe the change was a bit much for him.
I would like to once again thank all of your for your replies. I am new to this forum and you have all made me "feel at home" here. I guess we will just have to wait and see what his ears will do. I love him regardless.
