Dogs can be a great asset but I can think of a few issues they create. Aside from the issues of food & care, the one thing they are not great at is hiding and being quite. Teaching a dog the proper time to bark and not bark is difficult, at least it has been for me. My dog barks at appropriate times when someone is at the door unexpected or a stranger in the yard etc. She can’t distinguish between when it’s ok and not ok. Of course we haven’t been practicing crawling around in the bushes either.
