Neo-Paws:) Sam, my 13 year old lab, has had bone spurs for 6 years. He can only go for hikes when he wears his Neo Paws boots. With his boots on, he hikes over one mile a day; seven days a week, rain, snow or shine! He would be lost without his boots! They even stay on in mud and in the pool. Thank you !!! A great product!
