Thanks for the suggestion, but I can't imagine having a stranger in our house, taking care of our beloved dog. I did take a brief look at the website and it seemed too good to be true. That's a big red flag for me, but I'm glad it worked for you.
In case anyone is interested, this is what I have done and now do.
Twice I have left my dog with friends who insisted on taking care of him while we were gone. It was not a good thing for him or them. I will never do that again.
I much prefer leaving him at a well-regarded local pet boarding facility. He's stayed there so many times that he's excited to see the people who take care of him and totally ignores us when we drop him off. I just count the daily boarding fee as part of my trip expenses.
As for the house, we live an hour from the center of town by car. There is no public transportation. It's highly unlikely that anyone would want to stay here in the desert, with the typical desert wildlife.
It's even more unlikely that I would feel comfortable having anyone stay here. What if their ignorance of the environment results in them getting hurt? Would they sue us? What if it results in hurting our dog? I'd never forgive myself for leaving him with a stranger.
We do have neighbors. I tell them when we'll be gone. One usually has a key to the house and the code for the alarm in case of an emergency. I put some lights on timers in different rooms with different on and off times, so it looks like we are home.
I also contact the Sheriff with the dates for the trip, and someone drives by to check on things a few times while we're gone.
Those pieces of my home and dog care while I travel may sound complicated, but it is much simpler than house or dog training strangers.
