How is this done? I have a computer, an iPad, and an iPhone.
PetHub Forums (Beta)
Welcome! We are experimenting to see what level of participation we find when offering forums to our fellow pack members who want to share or ask advice around being pet owners. Please post your thoughts by creating a new topic or replying with a comment to an existing topic. It takes a village to raise our kids, including our four-legged furry kids. 
Thank you for being a member of our pack!

To scan the QR codes on the PetHub tag you will need a QR reader application.
Most newer phones have a QR code reader built into their cameras. If yours doesn't, you can always download an app.
PetHub doesn't have a specific app but there are multiple available in the app store for free for both Androids & iPhones!
