Adopting a dog in Kyoto

We just bought a house here in Kyoto and are thinking about adopting a dog.
But we are two foreigners from two different countries, so we want to travel to visit our families from time to time and have no friends or family who could keep the dog.
I looked at some of the dog hotels etc. here in Kyoto, but am not really sure how happy the dog would be there, because they mostly look like small apartment-like places.

Long term it would be nice to find someone in a similar situation (and with a similar way of caring for their dog) who could keep the dog while we are gone and whose dog we could keep when they are gone, but it might be difficult to find someone like that.

Does anyone have experience with the pet hotels and dog shelters near Kyoto, or any other advice?
