Pet Walker - Now Hiring

We need to have our sweet mini poodle, Benny, boarded, as we will be out of the country. Benni is the sweetest little dog, who acts just fine with us at home; however, when we boarded him with some friends a while ago, he was so stressed out and anxious that he did not eat for 3 days while we were gone. I am assuming it was due to other dogs being in the house, and he is very tied to us. Since then, I asked our vet to prescribe something for anxiety, and she gave him Trazodone. I am not sure if he would act like that if there were no dogs around. Can you please let me know if you do a meet-and-greet before the boarding? Thank you so much!
