3 month old puppy was v frustrated on first outing. Since then it's been v effective and she gets great enjoyment out of it and isn't swallowing her food in 3 gulps.
Saw great reviews about this feeder and was determined to get one through an Irish website. It stops my dog from hoovering up the food and becoming bloated. Very happy.
This was the only place where I've seen genuine outward hound slow feeder. It is saving my puppy from killing himself devouring kibble mixed with salmon moose/pumpkin/yogurt :)
