Kong Classic—I recommend a large for any dog over 30 pounds, which might only hold half their food. If you have a big lab or pittie, start with XL. I am also fond of feeding 3-4 medium sized Kongs and hiding them, or using them in a foraging game.
West Paw Toppl—The design winner, and my dogs’ favorite. The grabby parts on the inside make gushy foods stick and frozen meals take longer, but the open top is easier and, honestly, is probably more comfortable for a dog to lick out of. These aren’t cheap, though, at $20 a pop.
West Paw Quizl—This toy was designed to hold a bully stick, an application for which I have found it utterly unhelpful. You may have different results. What I do love the Quizl for is packing with wet food or raw ground meat and freezing. My resident interactive feeding expert loves this for a long project.
Busy Buddy Magic Mushroom—Of all the kibble puzzle toys I’ve tested, this is the one I’ve gotten the most mileage out of. My current mushroom has lived through six years of heavy use; it’s adjustable; it disassembles for easy dishwashing; it holds an entire meal’s worth of kibble. Definitely a winner.
Bark Busters Game Changer—If you don’t trust your dog with rigid plastic toys, this is a good option. It’s made out of a softer material, so isn’t as noisy on wood floors, is softer on a dog’s teeth, and much harder to chip or break. It can be a pain to open and close—it takes some practice—and can bend over time.
StarMark Bob-A-Lot—This is great for dogs who are gentler with their toys, or timid. Its movement is a lot less unpredictable than other food toys, and can be nudged with a nose or paw instead of flipped or thrown. This comes in multiple sizes as well.
Outward Hound Slow Feeder bowls—Nice, sturdy, and with no-slip bottoms. There are various patterns available. These are great alternatives for foods that you otherwise might have to put in a bowl: things that are soupy, messy, or soft.
