My dogs know suckers when they see them- ie, my mom, my husband, and any guest who "oooohhhhs" and "aaaaaahhhhhhs" over them. They don't beg much from me because they know that I don't like to share (unless I'm eating popcorn, which is fun to share! Then Marta will get on the back of the couch and rest her head on my shoulder and wait).

But, they beg like crazy when my mom is over because they know she is a sucker, and they know that my husband will certainly drop something. I'm definately thankful neither of them drool though!
