I purchased this from an online shop, but I've kept it stored without using it. ♦︎ Brand new, unused item! ^_^ [Supervised by a Veterinarian] The protrusions designed to prevent fast eating have curved shapes calculated to avoid stressing pets, with three different shapes (low, medium, and high) arranged in a balanced manner. We have received recommendations from veterinarians. [Easy to Wash] The moderately curved protrusions allow for easy cleaning with detergent and a sponge. Also, the material can be sterilized with boiling water, making it hygienic. [Non-Slip and Stable Structure] Non-slip rubber is attached to the underside, making it difficult to slide even if pushed by the nose during mealtime. [Durable Material] Made of a durable, scratch-resistant material, making it ideal for carrying around. [Product Specifications] M size: Approximately 20cm x 20cm x 4.5cm We have achieved the perfect size and weight for indoor use. We are committed to the health of pets and the ease of use for the buyer. ※ Depending on the dog breed, the pet may not be able to eat the food in the uneven parts due to the shape of their mouth and tongue. Especially for small dogs like Pomeranians, it may be difficult for their tongue to reach. Please check.
