I would like to print qr-code with transaction that contains my home address to print it for my dog's necklace. If dog will get lost everyone can scan it and get the address. How can I prepare the transaction?

Janina Lowisz of Bitnation's BlockchainID project became the first "World Citizen on the Blockchain" by making a sort of blockchain passport:
Something similar could be done for identifying pets.

Why don't you just print the address as a QR-Code? What's the benefit of it being on the blockchain, when you want people to scan it from your dog's necklace? – Murch – 2015-12-18T12:49:48.583
Because I want my dog to be the bitcoin user ;) – Xawery Wiśniowiecki – 2015-12-18T13:03:04.903
Is this to put a reward for finding your dog in the case that is is lost? If so, you'd need to put a private key, not the public address. The public address is what you pay TO. What good does having an address on the blockchain associated with your dog do? – morsecoder – 2015-12-18T13:45:50.167
Guys, it is just example to show how to prepare the transaction with custom message :P – Xawery Wiśniowiecki – 2015-12-18T13:51:35.120
Your example doesn't work and only makes the question confusing. There are no custom messages in transactions. – Jannes – 2015-12-18T14:19:21.093

I guess you could put an URL in the QR code that points to a blockchain explorer with a transaction ID. Still makes no sense though. Just make a website with your home address on it and make a QR code with the URL to that. Which still doesn't make sense. Why don't you create a vCard QR code? http://snapmyinfo.com/vcard/
