I think this will gently fit your dog's body, putting less strain on their neck and trachea. The outer layer is polyester, and the inner layer is mesh, so it can be used year-round. The mesh itself has considerable cushioning, so it should fit gently even when pulled. Adjustment is also possible with Velcro and tape, making it easier to fit the body. Choosing the size is very easy; just measure the circumference of the chest. Easy to put on and take off. Just put the front legs in and attach the Velcro and buckle on the back. I think it's very safe because it's supported by both Velcro and buckles. Chest size 24 to 28
