Thank you for viewing my products. Bone-shaped Length: Approximately 14cm Thickness: Approximately 2.5cm Donut-shaped Length: Approximately 9cm Thickness: Approximately 3cm All items are crocheted with acrylic yarn. Polyester is used for the stuffing. No squeakers are included. ★ The back of the donut-shaped toy is made in brown. Chewing can help teeth enter the gaps, which can be expected to have a teeth-cleaning effect, such as preventing plaque, tartar, and bad breath. Also, the bone-shaped toy is stuffed with plenty of cotton, so it has a good chew feel and can help relieve your dog's stress. Other shapes have less cotton and are softer, so I think even dogs with weak chewing power can play with them ^⁠_⁠^ ※ Please be sure to let your pet play under your supervision to prevent accidental ingestion. ★ We do not accept requests to change the colors of items from other sets. ※ We make each item carefully, but there may be slight size differences due to differences in yarn thickness. Please refrain from purchasing if you cannot understand this m(__)m #DogDentalToy
