Home Again Chip

Mom wants me to ask all of you if any of you know about Home Again chips. I have one from my previous family. Mom and Dad have the chip number and they know it's a Home Again chip, but they aren't sure what to do now. Do any of you have a Home Again chip? If so, do you know how Mom and Dad would change the info to the chip and is there a cost and any other info you might have for them. I don't run off, but I travel to so many different places with Mom and Dad and there's sometimes I'm off my leash at those places and since I already have the chip, then Mom decided to look into making sure the chip info is in Mom and Dad's name. I've only run off once and it scarred the crap out of Mom really bad. They were doing construction across the street and she kept yelling for me. (That's when she realized Kaos was a silly name for a dog. All the construction workers kept looking at her funny.) I just ran down to the park for a quick roll in the grass. The gate in the bak yard was broke and I was going to come back before Mom even realized I was gone, but Mom realized I was gone before I could get back. She was out in the front yard and when I came back she looked like she was going to cry and she hugged me, then she yelled at me. I don't run off like that anymore. Mom yells really loud and her face gets all red and her eyes look like they're going to pop out when she gets mad from worrying about me. She said she was worried the construction workers were going to run over me with their trucks. I promised I wouldn't do it again, but Dad fixed the gate that night just to make sure.
If any of you have any advice for Mom and Dad, they would really appreciate it. Mom said she's sure she could find the info on the internet, but she doesn't have time any more to search the internet for stuff because of her job and I'm not very good at it (I'm still looking for info on the monsters).
This has been a really boring week. Mom bougt the cheese for the Dogs With Blogs party this weekend. I home I'll be able to get on to join the chat, but Dad is planning on doing the transmission in the Big Jeep and Mom and I will have to help him with some things. I'm going to try to go to the chat even if it's just for a few minutes. I CAN'T WAIT!
