Designed for dogs weighing up to 4 kg and cats weighing up to 11 kg. Door series: for installation into doors or solid panels. Product dimensions can be found here.

This size (SM) is ideal for small dogs such as:

• Yorkshire Terrier
• Chihuahua
• Maltese 
• Pomeranian

The single hardened K9 COMPOSITE™ panel does not require a soft plastic replacement flap. It opens from left to right and with precision smoothness. This spring design allows even the smallest puppy or kitten to effortlessly push open the door. All four edges of the panel are equipped with high density, industrial nylon pile weather seal. This produces the highest level of energy efficiency when compared to other pet doors. 

Each time you open the door to let your dog in or out, heating and cooling escapes. Installing a PlexiDor pet door will save you money. Homeowners have reported their energy bills decreased 10% annually after installing a PlexiDor.

The hardened aluminium frames come in silver, white, or bronze finishes to coordinate beautifully with your appliances, interior walls, or floors. White and bronze frames have a baked on powder coated finish that is durable and scratch resistant just like the appliances in your home.

Small series does not come with a steel security plate. The spring loaded four-way lock can be set to IN ONLY, OUT ONLY, IN AND OUT, or LOCKED positions.

PlexiDor Performance Pet Doors are manufactured in the U.S.A. and comes with a manufacturer's 10 year limited residential warranty.
