little girls do NOT like slobber
That is
NOT true.
PRISSY little girls don't like slobber.
Normal little girls don't mind it a bit. They want to play.
My cousin's 5 year old, Ainsley, is PRISSY. She likes Bingo, her grandmother's horrible never shuts up talking dog because he's clean and neat and even when he kisses her, it's not very wet. He also doesn't shed much.
Her 3 year old sister Emmy is normal.
Em is friends with an enormous slobbery mutt that lives next door to their apartment complex. She introduced us while I was watching her while her mother went to the mall. He appears to be part yak and part slobber fountain, with a little Appaloosa thrown in for color. When she's outside, she runs to the fenceline and climbs up on the cable box. The part-yak runs over with his ball, and she stands there on top of the cable box, hanging on to her side of the fence, throwing the ball, and being slobbered all over every time it brings it back and stands up with his head and shoulders over the top to slurp her. He's a sweet dog--Em just calls him My Friend. But after 20 minutes of throwing the ball, she was slobber over 70% of her front. Didn't phase her a minute. All she said to me was, "Need clean shirts 'fore Mama comes home!" as we went to the apartment. OK, I was slobbery too. He was a lover!
Find Judge some nice, normal little girls to play with. They won't mind the slobber a bit.
But your friend's little girl probably needs a little de-prissifying before she plays with Judge again. Maybe a little mud-pie therapy would be in order??
