We used to send him to KENNEL while we were on the vocation.However,every time he gets back,he seems to be quite upset and kept a long time to be in a low mood.So we decided not to put him there this time,and that's very sweet of you to let him stay in your home for a couple days and made him well looked after. For once more,I should let you know that I ***reciated it very much!

Best wishes
