He does look like an Ardennais. I'm looking at the pictures in my book. Here's the description:
Roan, red-roan, iron grey, dark or liver chestnut are the preferred colors. Bay brown, light chestnut and palomino are admissible. Black dappled grey and all other colours are inadmissible.
Straight profile with slightly prominent eye sockets, low flat forehead, large expressive eyes, pricked ears and wide open nostrils medium length neck, well set on and generally arched, very strong shoulders, medium - heavy body with deep chest rather short back and muscular loins, wide rounded hindquarters fairly short strong and muscular limbs.
There is also another type known as the Auxois and a heavier framed Ardennais du Nord which came from crosses with the Belgian Draught.
That is so cool you have one! What's really cool about these horses is they were mentioned by Julius Caeser.
Unless it weighs a ton... it's just a horse. Draft horse motto.
