I have to add, the TM breed in general has a lower incidence of displaysia, cancers, seizures, and other genetic abnormalities than most other common medium-large breeds. There is occasional problems with ectropian, and there is a tendancy toward thyroid issues. There has been a recent upswing of some of these issues in the US lines however due to issues with importing new bloodlines, so care has to be taken in the choice of breeder.
They're also long lived. Over 10yrs is standard, over 12 is normal, and Apollo's great-grandma just turned 16 back in Dec.
