My last two dogs have been mixes but maybe at some point in my life I'll be privileged to have (in no particular order)
a Leonberger
a Portugese water dog
a Tibetan Terrrier
a soft coated wheaton
an Australian labradoodle
a Landseer
a Bernese Mountain Dog if anyone figures out how to make their lifespans longer

Quite a mix, now that I look at it - maybe that's why I keep ending up at the shelter!
