They used to cull all the stray dogs at the end of the tourist season in Corfu a number of years ago. Not sure if that still happens.
We found a stray with a paw ripped open in Corfu during one holiday so we took her back to our apartment, cleaned and dressed the wound and she slept on the rug at the side of my bed for the remainder of the evening. Then we asked the girls from the First Choice office to keep an eye on her so the dressing could be changed until it was fully healed.
One stray dog was adopted by the office staff and "Ella" used to come out on the weekly bar crawl night with the reps and visitors.
I haven't stayed at the hotel you asked about but TA seem to like it...
