Yes. As you noted, trained military dogs in medieval Europe had various roles in attack, defense, and as sidekicks. The centralized training, equipping, and distribution of the dogs shows that they were states' investments and did not just belong to individual nobles.
Animals in the Military asserts about dogs in battle:
"An invasion of Poland around AD 1250 by a coalition of Russians, Tartars, and Lithuanians purportedly included a large number of trained attack dogs."
"The Spaniards began using dogs at least by the 1260s, as King Jaume I of Aragon-Catalonia supplied guard dogs to garrisons of regional castles (Kaunanithy, 185)."
An article apparently by John J. Ensminger, discussing the book Dogs of the Conquest, says:
"... the Spanish Christians had used dogs against the Moors (Varner & Varner, p. xvi)."
"King Henry VIII was said to have sent hundreds of war dogs to the Emperor Charles V of Spain in a war with France, βeach garnished with good yron collarsβ (Lloyd 1948, Weir 2002, p. 33)."
The mentioned invasion of Poland was probably one of the several Mongol invasions of the 1200s. Genghis Khan is reputed to have used war dogs, but I have no good source on this yet.
