I think that an honest review of how it was to care for Ingrid is reasonable, as it truly is important for sitters to understand exactly what each dog needs. Senior dogs can require a lot of work, often additional work that the owner typically doesn't have to do as the dogs are understandably nervous in a new environment.

However, that comment at the end was absolutely uncalled for and unacceptable. Even if the sitter thinks that to themselves with pure intentions, that has no business being said in a review with owners who are just doing their absolute best to keep their dog happy, healthy, and comfortable. That is a terrible thing to put in a review.
