There are pros and cons to this aren't there? On the one hand you want a break. On the other hand at least this means you go on being fully involved in the family and don't risk being neglected as their lives get busier, as they need to see you each day at least twice to pick up the dog.
How about saying you need a break, and asking if it's possible to agree a complete break of a month once or twice a year when some other friend or service steps in to take care of things? Or even a 3 month sabbatical all at once to give you a taste of what you'd be doing with your days if you weren't helping them. You might even find you run out of things to do and welcome the return of the grandkids and dog. And it won't cost them as much as if you'd said a complete "no" right out. It keeps some options open and a compromise.
What a difference a day makes 😢😢
