You are assuming that "attack" means "bite."
But it doesn't, it should include those dogs that just have to jump all over people. Generally with that happens, the owner makes sure to tell you just how "friendly" their dog is being. Um, jumping all over me, isn't being friendly. Just like a human shouldn't be jumping all over me, nor should a dog. And owners that believe that their dog is just being friendly is exactly the type of owner that you described in your post.
So, yes. I will be on alert for dogs at a resort. I've been bit and scratched by a dog, ending up in the ER for treatment.
And yes, I will get enough information, including pictures/video/room location, if the owner does not have the dog under control. Because I will not allow another owner to be so oblivious that they ruin my vacation or life.
