My beagle's histrionic abilities

You know, ever since I adopted Trixie in 2010, I've been amazed with her theatrical skills. Every time we sit at the table for breakfast, lunch or dinner, she will approach us with sad gestures to see if she can get a bite of whatever we're eating. Beagles, of course, are famous for being driven by food. They'll do anything if they know they're going to get a treat as a reward. But if you feed your beagle every time he or she asks for food, in a few months you're going to have a pig instead of a dog. Just go to Google Image search and type 'fat beagles' to see what I mean. Of course, some dogs are obese due to thyroid problems and other medical conditions. But many beagles will get fat because of their obsession with food. Take a look at this picture:

This is Trixie with a typical "tragic" face ("Oh poor me, I'm starving to death and these people don't have a bit of pity to offer me a piece of what they're eating".) Sounds familiar, right? Sometimes, she will rest her lower jaw on my thighs to see if I get the message ("Can't you see that I'm dying to have a bit of what you're eating?") And when nothing else works, she'll start whining, yelping or even barking. But from what I've read, it' a typical beagle trait. That's why is so important to exercie them every day. If your dog is kind of lazy and doesn't want to walk around the neighbood because the weather is too hot (I'm posting this in the middle of summer), take the car and go to a park or another location. They'll quickly start to sniff their way around looking for new scents and at the same time they will do that walking they need so much.
