Brilliant. Whoever made that site is bloody hilarious:
Don’t Apply by Mouth. Many dogs resist their owners putting their hands down in the business sector, so you may need to get creative to earn compliance. If Fido resists, consider rolling it down with gentle, tender stroking motions. Don’t use your mouth to apply it. Although that may have served you well in college (regardless of gender), dogs find interspecies contact of this sort demoralizing, and even those that accept it find their regret so great they’re three-times as likely to wander into traffic thereafter.
