My puppy was eating his food too fast, resulting in him vomiting it back up. Instead of buying a slow-feed bowl, i drilled holes into a 12 in. length of 2 in. PVC pipe and capped the ends. I fill the tube with puppy food, and he has to roll it around to get the food to fall out of the holes. My puppy gets all the food he needs without the mess that comes from eating too fast. Be sure the holes are large enough for the food to come out!
