My vet says one of my guinea pigs is part beagle. We are trying to keep him at no more than three and a half pounds. I don't know about beagles, but I wonder sometimes if he mistakenly thinks he's a teacup poodle. He is a happy member of the Large and Ample Pig Society (LAPS). How fat are your lovely beasties? (We loved the linked pigtures here.)
