I paid $600 for Gizmo. Knowing what I have read on YT I know he was a byb who was referred to me by my neighbor. My neighbor has Gizmo's half brother and she had some issues when he was younger, he's now 1 yr old. Her dog started having issues after I got Gizmo. I did see the mom and dad and Gizmo is hyper just like his dad. I think I have been lucky with Gizmo. He had mites when we picked him up and he has had crystals, but I don't think any of those are something to blame on the breeder. I think I have been lucky with Gizmo and pray he will stay healthy. I didn't do any research before I got him, but I now know what to look for if I ever decide to get him a sister thanks to YT!
