My beagle is anything but little. She is extremely overweight. We rescued her from the shelter where she had been very abused. Our vet said he had never seen an abuse case quite like hers. She's been pushed beyond the level of fighting back.
But, she loves her chocolate ice cream. Yeah, yeah, I know, but that is an old wife's tale. Chocolate in the dose she gets from ice cream can't harm her. The most that would happen if she ate a large chocolate bar is she'd get diarhea.
