I've seen them advertising on terrific pets and couple other web sites like that..I don't know much about them..They do have nice looking dogs, large yes, but Danes in European countries do tend to be a lot bigger. They do show, and sounds like they may do health testing? So I can't imagine why they wouldn't have a guarentee longer than 6 months. They really don't have a whole lot on their website, so its hard to tell. I'd just email them if you want to know more about them.
