The Elizabethan collar, which owners reluctantly put on their beloved dogs after injuries or surgery to prevent them from licking or biting and worsening the affected area, can be a major source of stress for dogs. Large, rigid collars can also make it difficult for them to walk, adding to their stress. Post-surgery, they need to wear it for a minimum of two weeks. This is a recommended product that I finally found for the sake of my dog. ⭐️ Please inquire for other sizes and colors.
