opmart’s story begins with a wife’s love for dogs. The wife has a dog who has been with her for a long time. As the time goes by, the dog’s body gradually slows down, and the favorite sofa dog can’t jump up and down at will. The wife and husband said this, so the husband saw the stairs at home. He wondered if he could also design a stair for dogs, which would really help the dogs at home. Then he founded the Topmart brand, which is dedicated to developing more helpful products for various pets.
