How To Prevent Gaps Between Sliding And Dog Doors?
Installing a correctly sized dog door is essential to prevent gaps from appearing from the assembly. So here are some of the important factors to think about as you find the right dog door for your sliding door:

- Step over height: This element shouldn’t be over 1/3rd of your dog’s height.
- Door height: The fixture should be at least 1 inch taller than the dog’s height.
- Dog door width: The doorway's width should allow the pet to enter and exit the premises without getting hit by the frame.
