Buyer’s Guide
Choosing a pet door for a patio door is different than picking one for a wall or standard entry. Here’s what matters most for comfort, convenience, and year-round energy savings:
- Panel Style: Most patio pet doors come as a panel insert that fits into the track of your existing sliding glass door. No drilling or permanent changes needed!
- Insulation: Dual-pane, low-E, or insulated glass will help keep your heating and cooling bills down. Look for weather stripping and tight seals to prevent drafts.
- Adjustable Height: Your patio door’s track height is crucial—measure from the inside bottom to the inside top of the track for a perfect fit. Adjustable panels work for most standard doors, but always double-check.
- Security Features: The best doors come with locking covers, security bars, and anti-lift features to keep your home safe from intruders and wildlife.
- Ease of Installation: Most panels are designed for tool-free, reversible installation. Ideal for renters or those who don’t want to make permanent changes.
- Flap Size & Pet Comfort: Choose a flap size large enough for your biggest pet, but not so big you lose energy efficiency. The bottom of the flap should be low enough for smaller or older pets to step through easily.
- Frame & Glass Quality: Look for rust-proof aluminum frames and shatter-resistant or tempered glass for long-term durability.

FAQ Section
Will a patio pet door affect my door’s security?
Most panels include a locking cover and security bar, but your original sliding door lock may be blocked. Consider an auxiliary patio door lock for extra protection—easy to install and very secure.
Can I install a pet door if I’m renting?
Yes! Patio door panels are made for tool-free, non-permanent installation—no drilling or cutting required. Always check with your landlord, but most can be removed without a trace.
How do I measure my patio door for a pet panel?
Open your sliding door and measure the inside height of the track from the bottom (where the panel sits) to the top. Match this to your panel’s adjustable range for a tight, draft-free fit.
Will these doors let in cold or hot air?
High-end panels (like Endura Flap or Dragon) use insulated glass and weather seals for year-round comfort. Budget panels are less insulated but still reduce drafts compared to leaving the door open.
How do I lock my patio door with a pet panel installed?
Most panels include a security bar or bracket to keep the main sliding door from opening. For maximum security, consider an additional patio door lock, easily found online or at hardware stores.
