My puppy learned on day one using this product that it can tip it upside down to get the food out. I would not recommend this for a medium sized dog.This is a fantastic find. I have been having soooo many issues trying to get my dog to eat and weirdly enough, a slow feeder works! She is eating regularly without all of the interventions we had to do before, and it can stand up to our Lab puppies. This is worth absolutely every penny, thank you!Bought this for our Labradoodle puppy. This bowl has helped tremendously! It slows him down enough that he doesn’t get sick anymore. I can put a full scoop of food in it and it takes him long enough to eat that he doesn’t get a stomachache, saving me multiple trips to his food bowl with little tiny scoops of food. And he has gained a more appropriate amount of weight as he should have been.It’s great at keeping them from eating so fast but they slide around the floor the whole time they’re eating so you never know where they’ll end up. I guess exercising and eating is okMy French Bulldog puppy attacks her food and is a voracious eater, however this bowl has been quite effective at slowing down her eating. It is plastic and therefore not a heavy piece but it’s not expensive and it does the job. Would recommend for your little piggy, lolDidn’t make a difference
