By accessing or using DogAgeTool.org, you agree to be bound by these Terms of Service. If you do not agree, please do not use the site. It is really that simple. We are not trying to trick you into anything.
DogAgeTool provides free online calculators and educational content about canine aging, health, and breed-specific information. All tools run in your browser. We do not collect your dog's data. We do not store it. We do not even have a server that processes it.
We are not veterinarians. We do not provide medical advice, diagnosis, or treatment recommendations. Our calculators give statistical estimates based on research data. They are not crystal balls. They are not substitutes for professional veterinary care.
If your dog is sick, injured, or behaving abnormally, call a veterinarian. Not us. We will not answer medical questions via email because we are not qualified to do so.
Do not use this site for anything illegal. Do not try to hack it, scrape it, or overload it with automated requests. Do not use our content to build a competing calculator without permission. Just be a normal person using a normal website. That is all we ask.
The calculator code, design, and original content on this site are owned by DogAgeTool.org. You may share links to our tools and articles freely. You may not copy our code, republish our articles verbatim, or claim our research as your own.
The scientific research we cite is not ours — it belongs to the researchers who published it. We just summarize it and make it accessible.
Some blog posts contain affiliate links to pet products on Amazon, Chewy, or other retailers. If you click these links and make a purchase, we may earn a small commission at no extra cost to you. We only recommend products we have researched or would actually use.
To the maximum extent permitted by law, DogAgeTool.org and its team members are not liable for any damages arising from your use of this website. This includes but is not limited to: health decisions made based on calculator results, financial losses from affiliate purchases, or emotional distress from realizing your Great Dane is biologically older than you thought.
We may update these terms occasionally. When we do, we will change the date at the top. We will not email you because we do not have your email. Continued use of the site after changes means you accept the new terms.
These terms are governed by the laws of the State of Oregon, USA, because that is where Mark lives and he built this thing. Any disputes will be resolved in the courts of Oregon.
Questions about these terms? Email us at privacy@dogagetool.org. We typically respond within 48 hours unless one of our dogs has an emergency.
