I am watching a friend's Yorkie Baby this week...she goes home today.

She was a little off her game...but mostly she as adjusted well and has loved playing with the Baby Roxy. She has come over for a day hee and there before...so she knows me and the family. She has her toys...her food...and all her personal things. Mommy only forgot her favorite blanket...but she haqs done well.
I think this is ideal...she is kept on a schedual whee she can hang out with people and other pups. She gets to sit on laps and get's talked to and taken walks.
I went on a vacation a few years ago and left my Scottie in a doggie hotel. air conditioned room with a bed, TV and 2 play 20 minute play periods a day. She loved it ....always happy to see her people. (or acted like it anyway) I could have payed for more play time outside...and there was a website with live action cam to watch/check in on her.
I worry about leaving Roxy next summer for a trip...I am figuring that one out as I type. lol
