My first visit to Dave and Aimy's was a nice welcome, run down at the door by their blue Great Dane, Ruben. He's now 8 months old, stands as tall as my chest and weighs more than I do. I told them their house is something like a petty zoo with two dogs, two cats, fish and a small pony in their house. He acts like a puppy but is stronger than he knows. His tail and "gentle bumps" to be pet nearly knock me over if I am not braced. I'm curious to know how strong and big he'll be full grown!
