Dog Panty Pattern Needed

I need a pattern to sew some dog panties for my Pug, Chloe.
She is in heat, and all that is available is those nasty 4 seasons
plastic belt type things. She would look super in a overall bib, but
I cannot find any on the net or anywhere. If anyone has anything,
can you help me out there?

Pugs are great. They love being dressed. We also have a black
one (Miss Dottie) who gets her own junk mail delivered to the house.
She has many coats, and hats to match. Think of Princess Di and
her matching outfits.

We also have adopted a Mastiff. His name is Atti, and he is terrified
of the chickens, and especially the geese who chase him around the
yard.
Regards,
