Medium to Large Dog Collar Cushion Choke Collar Iron Baron Selling Price: 3300 yen I am listing this at the request of a family member. They purchased it for a large retriever, but it was too small, so it has hardly been used. The cushion material reduces the burden on the neck, and it is also recommended for walking dogs that tend to pull. House cleaned with OxiClean detergent. Neck size: 50cm In my personal opinion, It is recommended for large dogs that are underweight (up to 25kg) or puppies under 1 year old.
