What a sweet photo of four Fjord ponies pulling a sled in Canada. Fjords are a stocky draft-type horse (or pony - they are short in stature, but due to their strength are often referred to as horses). Their distinctive dorsal stripe is traditionally shown off by trimming the mane to stand up, so the black stripe is clearly visible. Originating in Norway, the Fjord is now quite popular throughout the US and Europe, both as a driving or draft animal and for pleasure riding.
