This guide by Ollie covers beagle pros and cons, what is going on under that velvet-eared exterior, and how to feed a beagle so the breed’s biggest health risk never becomes your problem. This matters because beagle weight management is not a vanity project. The encouraging flip side: Weight is the one major beagle health lever that is almost entirely in your hands. Whole-food ingredients and adequate protein and fiber help a beagle feel satisfied on an appropriate number of calories.
