Slow down a fast eater
Snufflers (Snuffle Mats) are a very effective way of slowing down a fast eater. Ari, a Kelpie x Border Collie who we fostered for 5 months was an exceptionally fast eater. She would inhale her food in seconds and then hiccup for ages afterwards. We changed to a slow bowl but with her skinny muzzle it barely slowed her down at all so we started feeding her in her Snuffler with terrific results. It slowed her feeding from seconds to around 5 minutes and no more hiccups.
