Elizabethan collars, which owners reluctantly put on their beloved dogs after injuries or surgeries to prevent them from licking or biting and worsening the affected area, can be a major source of stress for dogs. Collars with a large outer diameter and that are hard can also cause stress by making it difficult to walk. Post-surgery, they need to be worn for a minimum of two weeks. This is a recommended product that I finally found for my beloved dog. ⭐️Please inquire for other sizes and colors.
