Biggest dog I've ever had - Presa Canario, weighing in around 100 lbs.

Heaviest, Boxer, full champion, about 130-150, depending on what week it was.

When I had my Presa (Bella), I was 18. My size 30 belt would barely fit around her chest. Due to the area I lived in at the time, I wasn't able to keep her. (Presae are a banned breed in many communities and cities.)

The Boxer (El Jefe) Wasn't that large, but he was bulky. And he loved to "box". He'd stand on his back legs and try to swing his front paws at me while I practiced kickboxing. Eventually, I started practicing (jokingly) with the dog... he learned pretty quickly to duck his head and swing afterward.
