My first response to this is...if you have to ask if you have a communication problem...you probably do.
I have one obvious question here for you....and I'm sorry to hear about your dog, I know how that hurts.
Did you tell your H you would like to help bury your dog? If not, he truly may have thought he was sparing you some pain. So to answer your question, IMHO, yes...you have a communication problem.
From what you posted I interpereted it to be he was trying to be helpful, especially if you didn't say..."honey I want to be there to help bury our dog, it will make me feel much better to help do that." He's not going to assume doing this would make you feel better, or help you heal. And asking if he was waiting for you to come home before he did this...still isn't stating "I want to help". This, to me anyway...would still sound like a hint that you would want it done before you get home. But that's just my take on it.
A year ago one of our beloved cats died (feline leukemia) it really tore me up, my H was really attached to her too. He made sure she was buried in a good spot before I came home (we too live in the country)....it was his way of trying to be helpful for me.
So don't be angry at him for what he did...I am almost positive what he did came from a good place in his heart, and that he was thinking of your well-being when he did it. He, I'm sure, didn't intend to hurt or anger you.
