I am willing to bet that 99% of your local college students fail to understand basic dog psychology.
That demographic makes the same mistakes with the toy breeds.
“Oh, I’m sorry. You can’t sit there. It upsets Fifi.” (Small dog growls at guest, is not rebuked by owner).
You have ignorant dog owner problems, not a dog problem.
I’m willing to bet that the “99% statistic” is crap.
