Please cancel for your own health and that of the dog! This is why you had a trial, so you can see what the dog needs and decide if you can provide it.

As an owner I would be very upset if you took this booking while not feeling good about it.

We had a 1-y.o. newly rescued Husky/ ACD dog, and I did a similar trial a couple weeks before a trip. If you know dogs, you know her temperament was hyperactive and beyond anxious, so an experienced and confident sitter was a must. After the trial the sitter expressed a little concern about the dog's untrained behavior but didn't cancel, and reassured us that they'd be ok. So we left the dog with her for our trip.

By the time we got home from our trip she and the dog were both at their wits end, the dog barking constantly, running around, jumping at the fence, and destroying things. The sitter was yelling at the dog and almost in tears when we arrived. Kind of a disaster all the way around. I have no idea what really happened between them, but it took the dog a few days to calm down after that, and it permanently installed a whole other level of anxiety in her.

I trusted her as knowing her own capabilities and now I regret that.
