Before You Buy
Key Buying Factors
01
Size and Adjustability
Ensure the door or gate fits your door frame and allows room for your puppy to grow. Look for adjustable width or height.
02
Material Durability
Puppies chew and scratch. Choose weather-resistant plastic or sturdy metal. Plastic doors should be thick and impact-resistant.
03
Ease of Installation
Look for tools-free or simple mounting. Tension-mounted gates are easy to move, while wall-mounted doors require drilling.
04
Safety Features
Look for smooth edges, pet-safe flaps, and locking mechanisms. Avoid doors that can pinch or trap your puppy.
05
Pet Door Accessibility
If a gate has a small pet door, ensure it's high enough for your puppy but low enough that it won't get stuck.
06
Training Integration
Doorbell-style products help signal potty breaks. Ensure the bells are audible and easy for your puppy to reach and touch.
Living With It
Care, Cost and Maintenance
Clean Regularly
Wipe down the door flap or bells with mild soap and water to prevent odor buildup and ensure longevity.
Check for Wear
Inspect hinges, flaps, and mounting brackets monthly. Replace any parts that show cracks or sharp edges that could harm your puppy.
Adjust as Your Puppy Grows
For gates and doors, check fit every few months. Many products allow height or width adjustments to accommodate a larger dog.
Pro tip
When installing a plastic pet door, position it so the flap is at least a few inches off the ground to prevent drafts, but low enough for your puppy to push through easily. Train your pup to use it by propping the flap open at first.
Frequently asked questions
At what age can I start using a dog door for my puppy?
We recommend waiting until your puppy is at least 4-6 months old and has basic potty training. For doorbell training, you can start as early as 8 weeks with supervision.
Are plastic dog doors safe for puppies?
Yes, if properly installed and made from high-quality, non-toxic materials. Look for flexible flaps that won't pinch and have rounded edges.
How do I train my puppy to use a dog door or bells?
Start by associating the door with positive experiences. For bells, hang them low and encourage your puppy to nudge them with their nose or paw, then treat and go outside quickly.
Can I install a pet door in a rented home?
Tension-mounted gates or removable doorbell hangers are best for rentals. Plastic pet doors require cutting, so check your lease or use a model that fits in a sliding glass door track.
What is the best way to clean training bells?
Wipe the bells with a damp cloth and mild soap. Avoid submerging them in water as the clapper may rust. Dry thoroughly before rehanging.
