We don't like boarding our dogs. We took them in once for a few days and put them in same pen together, thinking that they would be more calm if they were with each other. When we went to pick them up, the Vet said they had to separate them into separate pens because they were fighting each other - I have NEVER seen them fight each other at home. Our yellow lab is a nervous feller anyway, and I've heard stories of dogs getting so upset from being boarded that they have health issues.
We tried a paid service that would come feed, water, and play with them when we were gone, but that was a bust, too. I should have known it wouldn't work when she showed up to get the house key and she was wearing white pants, high heels, and some fluffy shirt (true southern belle fashion). BTW, our dogs are labs, live outside 100% of the time, and are typical high-energy labs. When we got back into town, they lady left a note that the dogs "tried to trip me". "Yes, ma'am, my dogs had a plot to trip you when they saw you coming. They've been planning it for weeks."
Nowadays, we get one of Rachel's friends (apparently I can't seem to find anyone around here that is worthy of my friendship) to come over and water and feed them when we are gone. She's around them enough that she knows what she's getting in to and how to handle them. In return, we dog-sat her little yippie dog for two weeks.
When my parents' cat was still around, they had an automatic feeder that was on a timer and a water bowl that recirculated the water to keep it fresh-ish. That was good enough for them to be gone for 2-3 days. Any longer and they got one of the neighbor kids to come clean the litter box or put out another litter box if the cat wanted a 'fresh' spot.
