Johnson Dog Doors was acquired by PetSafe Pet Products in 1998. PetSafe is the world leader in Electronic Pet Training and now is the world leader in dog and cat doors. In fact, our pet doors have been the most popular pet doors in the U.S. since 1952! While the name may have changed, the quality continues. A PetSafe Dog Door lets your pets come and go, as you please; so you can put an end to late night trips to let your pet out....AND, no more scratched doors or walls. No more "accidents" on carpets and drapes. Pet owners love our doors because the flexible, two way panel is safe for any pet. The soft vinyl flap won't trap or injure tender paws, ears or tails....AND, the permanent magnets assure you of a draft-free, energy efficient closure. The translucent vinyl panel makes it easy to train your pet to use a PetSafe Dog Door. Once your pet has learned about its new freedom, your pet will set its own schedule-and not be dependent on you to let it in or out. Your pet will come and go freely, so it can get exercise outside, yet come inside for shelter from heat or inclement weather. Please review our complete line of pet doors.
