I've used this with my Toy Poodle a few times, but he doesn't seem very interested in it. So, if anyone wants it, please take it. I washed the washable parts with dish soap, and disinfected them with alcohol before storing. I think it can still be used. Please refrain from purchasing if you are concerned about hygiene. Due to the price reduction, it will be simply packaged without cushioning material. Think, rotate, and eat! This is a gachapon-style educational toy. It stimulates the desire to eat through "smell," "sight," and "hearing." It's a size that's easy for small dogs to play with, allowing them to train while having fun♪ There are six different food hole sizes, ranging from 11 to 16 mm in diameter, so you can use the food you already have at home! The zigzag slits firmly secure the rotating drum! Yet, it's easy to remove by simply zigzagging. You can disassemble the parts and wash them completely, so you can use them hygienically. The gray nose work toy has one of the rubber pieces on the back detached, but it doesn't affect its use.
