A great tactic i use is what i call Fox Hunting. I have 2 Dog Companies and maybe 2-3 Horse Companies. What i do is use the dogs for tying up troops charging my horses or to cause chaos within enemy ranks. This even allows me to charge in the front of units that has spears. Since theyre all tied up with the dogs. When the unit route i let the dogs do the chasing of the "fox" and save fatigue for my horse that can turn their attention to the battlefield.
