I only opened it once to try it on. I am selling it because I purchased the wrong size. ▽Product Information Dog Walking Assistance: This care harness helps senior dogs, dogs with illnesses or injuries, and dogs with mobility issues who have weak legs and hips to climb stairs, walk outside, and get into cars. Full Body Design: The stress points are distributed across the dog's chest and torso, without excessive pressure on the neck, legs, and shoulders, allowing for more comfortable support for the dog. It can also be used as an aid for nail trimming, etc. Comfortable and Highly Breathable: The outer fabric is Oxford cloth, and the lining uses breathable mesh material, making it less stuffy, comfortable, and durable. The handle with removable padding widens the area of force and is comfortable without squeezing the hands. Unisex: Both male and female dogs are suitable for this care harness, and the bottom-open design does not affect the dog's daily elimination. Adjustable: This dog assistance harness can be worn over the shoulder or held by hand by adjusting the length. Also, you can adjust the looseness to some extent according to your dog's size with the three buckles on the back. The weight is only a guide, so we recommend that you refer to the size chart and measure the exact size before purchasing.
