They were helpful and professional. The pet door looks and works great in my sliding door and my puppy loves going in and out as she pleases. It only took her a couple days to master it. It closes very securely and stays closed even with lots of wind (we live at the point of the mountain where we get tons of wind). I also don’t feel any heat/cooling loss through it. Overall great door and experience! ![google](https://petdoorproducts.com/wp-content/plugins/wp-social-reviews/assets/images/icon/icon-google-small.png) [Ron Pinarelli](https://search.google.com/local/reviews?placeid=ChIJN8IABB6LUocRyP02-wi3F_I) August 27, 2025 Stayed with schedule install was fast and no problems cleaned up and they were gone ## Frequently Asked Questions When selecting a pet door for a growing puppy, it’s best to base your measurement on their estimated **full-grown size** — not their current height and width. Consult your vet or breed-specific growth charts for guidance. Choosing a door that matches their adult size ensures long-term comfort, usability, and avoids needing a costly upgrade later. A door that’s too small can be difficult to use and cause anxiety or injury. For extra peace of mind, our team can help you choose the ideal size — just [request a quote](https://petdoorproducts.com/request-quote/) and mention your pet’s age and breed. We recommend choosing a door size that fits your **largest pet** comfortably. Smaller pets typically adapt quickly and learn to navigate slightly larger doors with ease. For example, a medium-sized dog door might be perfect for a lab and still workable for your smaller terrier. If your pets are extremely different in size (e.g., a large dog and a very small cat), we’re happy to recommend a balanced solution — or even dual-door setups depending on your needs. Our [guide to pet doors for multi-pet homes](https://petdoorproducts.com/multiple-pets-one-door-complete-guide-to-pet-doors-for-multi-pet-homes/) offers more insight. Not with Pet Door Products. All of our doors — regardless of size — are designed with **energy efficiency** in mind.
