This is a knit hat for dogs with ear holes. It's knitted with straight needles, so it's softer and more stretchy than those made with crochet. The face and neck are ribbed, and the top of the head is stockinette stitch. It has a size-adjustable string to prevent it from slipping. ■Size Face circumference: 35cm-38cm Please measure the circumference of your dog's head, from the base of one ear, across the forehead, under the chin, and back around. ■Materials Main body: Wool blend (100% wool and a blend of 70% wool and 30% acrylic) Pom-pom: Acrylic As this is a handmade item, it is not perfect like commercially available products. Each one is carefully knitted, but there may be some loose thread ends or slight irregularities in the stitch pattern. Knit products may unravel or tear if pulled strongly or subjected to impact. Please hand wash in lukewarm water and avoid wringing. Since hanging can cause stretching, remove excess water with a towel and dry flat. It will be shipped via Yu-Packet Post Mini. It will arrive flattened, but please note that it will return to its original shape if you shake it gently or steam it.
