See, this is the problem we get into.
You say that the dogs are noisy. I, as the player, say, no, I bought trained dogs that were trained to be quiet.
How do you resolve that?
I would give you the opportunity to know that. Did you buy them sight unseen? Then you get what you get. Can your character be reasonably expected to know about dogs? I give the benefit of the doubt on that... so your background could help you there. And the main thing: did you think to ask about it when you were buying them?
That's where we get back to it being a game. If you thought to ask, or if circumstances were such that you could have known, you'd get the info. If you just went off half-cocked and bought the first bunch of war dogs you ran into, then you get what you get. And if the only dogs available are noisy dogs and you find that out then you have an interesting decision to make.
You could also invest in muzzles. Or (if playing standard D&D) have someone cast Silence 15'r on a dog collar, and send the dog handler out ahead of the group.
Everything that comes up should be an opportunity to make an interesting trade-off or come up with an inventive solution. Since the Referee is in charge of the world, it's his responsibility to keep up that pace. And also, when to the players come up with a really good idea, to let them benefit from it.
