Well, well, well. Noobing it up so I can join in on the discussion.
I'm the sister-in-law. I'm also the best friend, so Ms. Fancy Pants can just dump the formality already. To clear up: YES, the fabulous King Charles is welcome to attend. I grew up with Cocker Spaniels myself (you know, the dumber versions of yours) so I'm happy to welcome your baby in to my home. Any non dog related questions can still be directed towards Joanne, and yes, there is some crash space here.
I'm looking forward to meeting you on Saturday!
