I’m sure you are delighted to receive their invitation...tell them that.
Gently Remind them of the distress from your last visit and, at the same time, you realise their love for their pets....they are, after all, their family.
Be honest in saying you don’t want to upset the dogs again so wonder whether they will be roaming around.

If the dogs will be settled somewhere....have fun...maybe take a little treat for the dogs to show that you respect their family.
