What can Dog Age 2 do?

DogAge2 is a web app for creating pet cards for dogs and cats, collecting other pets' cards in a holder, and managing ages.
You can use a pet card like a digital pet business card, hand it out by QR code or URL, and show both real age and a human-age estimate from the birthday.

What is age management?

It is hard to tell the age of a dog or cat from its appearance, isn't it? By entering the date of birth, it is possible to display the age of the animal, as well as the human-age being. The human-age is calculated more precisely using a unique calculation method based on the growth curve to adulthood and the average life span of each breed of dog (cat).You can try the human-age calculation using the form below.

What is a pet card?

A pet card is a card for pets that you can keep on your phone. It can work like a pet business card or digital pet business card, and you can also save cards you receive in a holder.
Unlike paper business cards, cards can be handed out for free as many times as you like, and the contents can be updated after handing them out, so you can keep people informed and link to Social Media (Instagram, Twitter and YouTube).

How can I hand out a card?

Tap the QR code on the back of a pet card to copy its card URL (https://da.uda2.com/(7-digit number)/). You can hand out the card from your phone by showing the QR code or sending the URL.
Specifically, the following methods are possible.

  • Display the card on your phone and have it read the QR code that appears on the back.
  • Put a sticker with a QR code on your pet's ID tag or kennel.
  • Print the QR code on a paper pet business card.
  • Send the card URL by email or social media.
  • Use an NFC tag that opens the card URL when scanned.
