Pensioni per cani (pet hotel) (Rome)

Hi guys, I am currently looking for dog hotels in and around rome...but so far it seems to be very difficult to find one that has no boxes outside and would be suitable for our furry kids.
We're used to a more indoor living and outside playing kind of place. so far....I couldn't find one that is like the ones we know from back home (USA).
Anybody an idea...since most of them wouldn't even take our dogs in mid of April since they're not used to living outside, colder temperatures and what not.
Would love to hear your feedback, experiences and ideas!
Mille grazie!
