we've been on both sides..........
we boarded our one (at that time) dog at a breeder's home for $50 a day (including food, etc). we checked out the home, her other dogs, etc first. blackie (a pure white shepherd, btw

) absolutely LOVED it ~ her dogs & mine "hung out" together in the house & fenced yard, constantly supervised (she did have a run, but they all got along so well, there was no need to seperate them). her dogs had proof of all shots ~ i checked

, as did mine. btw, we justified the higher expense over a kennel because of the extra attention & care a "home boarding" situation would give our four-legged family member.
now, sending our 2 goldens "on vacation" would cost over $100 day (& we norm go for 12 days), so my parents take care of them in our home. they come at least 2X daily ~ feed them, let them out, & most importantly: play with them. since my 2 cats need to be taken care of
(somewhat

), & fish fed , they can "do it all".
my now 19yo DD has taken care of our neighbors 2 cats for about 10 years. she goes there at least 2-3x daily, no less than an hour each time. she feed them, changes the litter boxes, waters plants, brings in the mail/newspaper, brings out garbage, & does any small tasks asked. the most important part (in my eyes, as well as the neighbors') is that she plays with the cats, cuddles them, & makes sure they know that they're very much loved even if "mom & dad" have gone away for a bit. since we've always had pets, she is very much aware if anything appears wrong with the cats.
she gets about $20-25 day (she's never asked for compensation & would do it for free, but they insist saying, "she's worth much more"), plus they give her movie tix, or some sort of souvie (water bottles, t-shirts, etc).
main points: check references, check EVERYTHING!, make sure whoever watches your baby will take care of them at least half as well as you do.
