So it's a small owner run business. Just what I'm looking for myself in about 5 years time.
Go with your gut, if you liked her and the dogs were active then I'd say it's as good as your going to get.
But again she may come home with the runs and this is normal for some dogs.
I used to take Gemma and Kelsey to work with me all the time. They could stay anywhere and slot right in.
If for instance Poppy was to stay for a month she would probably have the runs, it would settle and she would come home OK. Often it's the shorter stays that upset the dog.
Give them all your holiday contact numbers and phone daily to check on Poppy. I used to speak to lots of owners to reassure them their baby was doing OK.
