So what has been happening with the dog up to now? Were you looking after grandson and dog at his house, or at yours?
If you like dogs you could let your daughter drop it off to you, as long as you can leave it at your house alone if you want to go out (yes dog hairs etc I know), and stipulate that she has to walk it when she gets back, or find a dog walker , on the days when you do not want to, or cannot, take it out yourselves.
Or maybe agree to look after dog once or twice a week, but leave some days to yourselves. Daughter has just got used to the idea that your purpose in life is to be there as a stand in mum for her family. If she didn't even consult you before accepting the job she needs a wake up call. You and DH need to relax and enjoy life while you still can (hopefully for many more decades).
A super-quick, easy dinner for Gdcs when you’ve all been out all day and they’re ‘starving’….
