I wonder what breed it is? I can't see it very clearly, but it looks smaller than a German Shepherd. Do you know, Katie77?
It's a Malinois. Belgian Shepherd Dog.
A bit smaller and lighter built than German Shepherds, the face more pointed (sharp?, fox-like?), but similar in proportions.
There are four variations of Belgian Shepherds:
Groenendael
Laekenois
Malinois
Tervuren
Malis (their name is shortened to Mali) are very, very popular for the use as police dogs. In many countries they overtook the GSD for this use because many blood-lines of the GSD are simply ruined for the use as working dogs. They have been downbred for "beauty" and to fit on the sofa.
Malis are more agil and have more fierceness than most blood-lines of the GSD. The GSD basically is split into two breeds today: working lines (thankfully they still exist, breeders whose utmost goal is to breed dogs suitable for serious work) and show lines.
The Mali is a wonderful dog, but he needs to work. Otherwise they tend to get aggressive and/or destructive. Exceptions prove the rule, as always.
