A U-shaped neck pillow made of breathable mesh material. Specifically for pets. I bought it for my dog for caregiving, but it was too big and he passed away soon after, so it's still brand new and unused. I think it would be just right for dogs weighing 4-10 kg. - Shape: U-shaped - Color: Beige - Material: Mesh material - Use: Neck pillow Dog pillow Pillow Dog cushion Caregiving Senior dog Service dog Thank you for looking.
