Outward Hound slow feeder food bowl. Reduces the risk of regurgitation, obesity, and bloat. Non-slip bottom. Diameter: Approximately 13cm Height: Approximately 3cm I bought this to prevent fast eating, but it was a little too big for my dog, so I only used it once and haven't used it since, so I'm selling it. Please check the photos for the condition! If you don't need it, I will also include a food sample I received when I purchased the bowl. The expiration date is April 2026. Thank you.
