Keep Your Giant Breed Dog Safe and Secure with Our Patio Insert

Perfect Fit for Your Giant Breed Dog

Our patio insert is designed to fit any sliding door system with height ranges from 70 inches up to 99 inches. This means that no matter what size your door is, we have you covered. The pet opening is generously sized at 15" inches wide x 28" inches high, making it easy for your extra large to giant breed dog to pass through comfortably. We offer four different step over rise options so that you can customize the height of the pet opening to match your dog's size and mobility.

Superior Quality Hand Built to Order

At Security Boss, we take pride in the quality of our products. Each patio insert is hand built to order with the highest attention to detail. We use only the best materials to ensure that our products last for years to come. Our patio insert for extra large to giant breed dogs is no exception. It is made with durable materials that can withstand even the toughest wear and tear. This means that you can have peace of mind knowing that your furry friend is safe and secure.

Keep Your Dog's Health in Mind

As responsible pet owners, we understand the importance of our furry friend's health. That is why we designed our patio insert with your dog's mobility in mind. The step over rise should be easy for your dog to step over, and we recommend that you choose a height that will be easy for them to manage as they age. This is especially important for certain breeds that are more prone to arthritis and hip problems. With our patio insert, you can ensure that your furry friend has the freedom to come and go as they please, while also keeping their health in mind.
