We have a black lab/great dane mix (at least that's what the vet thinks, he was an SPCA rescue). He's pretty skinny, like danes usually are, but still weighs about 75lbs. When standing on his hind legs, he's about as tall as me (5'9"), he's a big boy.
We recently adopted a 75lb greyhound and he is really skinny.
Our other dog is an unknown mix (dumped as a single puppy at a shelter so no idea about the mother). They thought maybe a Dutch Shepherd mix and the vet estimated 50lb, but she's full grown now and only 26lb.
