Dear Cathy,
I am writing to express our heartfelt thanks for your taking good care of Smart while we were on vacation.
He was such a happy dog when we got home.We knew he must have had lots of loving attention.When we picked him up from the kennel in your home he would whimper and carryon for hours.
You not only saved us some money,but also spared us the worry about him while we were away.Your kind help is very appreciated,not only by Smart,but also by our whole family.Please accept our thanks again.
Yours sincerely,
Li Ming
