This is another one from the 'Rare Dog Breeds' series that I drew a couple of years ago.
Terriers are renowned for thinking that they are a big dog in a smaller dog's body, and perfectly willing to have a go at dogs a lot bigger than them...often much to their owner's dismay!
I thought about how I could exaggerate this idea and eventually came up with the idea of the rhino with the terrier handing onto the horn. The rhino looks none too pleased....
