My dog growls all the time. is it normal?

Maybe he see's ghosts...

Is it a small dog that travels in a purse? They're horrible ill tempered little things.

But if it's an actual dog then I'm stumped.

Some breeds do have their own noises that they tend to make. My dog makes an odd noise that sounds like a growl when she is pleased to see you or is trying to get your attention (want to play, go out etc) but it tends to be something her breed does, it's not an actual growl.

Some dogs depending on their breed are said to comunicate in that way...

yes my dogs growl, howl and bark when they want to tell me something. i always think of Lassie and make jokes that Sunny got stuck down a well and for us to go and find him lol. that is just how they talk :)

We tend to think of dogs as simple. They're not. They have different personalities just the same as we do, and they can have strange traits just the same as we do. I'm not saying there's anything wrong with your dog, by the way, just that dogs are like people. All different. Look at the different people on this website. I can think of a few who'd growl even if they were happy.

Maybe it's his way of talking. Even when dogs growl each growl may have a different quality or sound to it.
