This product offers two types of Elizabethan collars: "2-in-1 Elizabethan Collar" and "Bell Type" and "Donut Type." You can freely choose the type that best suits your dog or cat's condition. The bell type is recommended for cases of severe itching, after surgeries like spaying or neutering, or if the affected area is on the legs or tail. The donut type is recommended for preventing licking from the head to the waist and scratching of the neck and back of the head. "Soft Material": The neck area uses soft PP cotton material, providing a fluffy feel that allows your cat or dog to relax. Sponge material is used inside the sides, so it can also be used as a pillow when your dog sleeps. "Adjustable Size": The collar is easy to put on and take off with a one-touch Velcro closure, and fine adjustments can be made with the adjuster. There's no need to worry about it being too loose and coming off or too tight and uncomfortable. The baby-grade Velcro won't damage your pet's fur. "Easy Care": The sides of the Elizabethan collar have stain-resistant and water-repellent functions, so you can easily wipe the inside clean if it gets dirty during meals. It's also easy to remove hair, can be washed in the washing machine, and can be stored compactly when not in use, which are key features of this product. "Product Information" S size: Neck circumference 15-24cm, collar width 9cm, weight 53g, recommended weight 1-3Kg. Before selecting a size, measure your pet's neck circumference and choose a size that allows two fingers to fit between the neck and the collar.
