How exciting...I smiled when I pictured your dad out there measuring the fence!

You'll get lots of pointers...but I would think introducing a new dog is similar to intro'ing any new animal. Keep Sugar in her own space, away from the cats for a while. Get a towel with her scent on it, and let the cats smell it - and vice versa.

From her writeup, seems like she would love to play with the kitties - but they may not be of the same mind!

Mostly, give them time and space.

HUGS to the newbie!
