What matters most for the money

Value in a dog door comes from a weatherproof seal, a durable flap and a frame that fits without endless draughts, rather than the lowest price. A natural timber surround looks tidy and lasts if treated, while a tough flap that does not crack in cold weather saves replacements. Measure your dog and buy for the largest dog using it, since a too-small flap is a daily struggle.

Think about long-term running costs too. A well-sealed door keeps heating bills down, and a magnetic or weighted flap closes cleanly behind your dog. A locking panel adds security without much outlay. Spend a little more on a flap that resists chewing and UV if it faces the garden, because a brittle flap is a poor saving. Introduce it patiently with treats so your dog learns to use it confidently and the investment pays off.
