How to choose the appropriate size for your dog
Keep the dog standing
Measure the maximum width of the dog (chest or abdomen – based on the dog’s body size)
Measure the maximum height of the dog (from ankle to the highest point on the back)
Compare the size of the door opening to ensure that the dog can pass through
Tip: If your dog’s body size is close to the size of a dog hole, we recommend purchasing a larger size to make it more comfortable for your dog to pass through.
