Not sure if this is the right place for it, but anyway...
I presume that of the alien types shown in the first three movies (excluding the obviously large gueen), the Big Chap and the warrior are the same size.
But how large was the dog alien in comparison to Big Chap.
He can look quite small on all fours, and although he has a long tail, he's quite slim.
Who has the larger head? Who's bulkier?
Dunno if anybody has anything definitive on anything like this,
