That's not typically what we call happy tail. Happy Tail is when a dog wags so hard they hit their tail on objects and walls and break the skin or even break the bone.
I had a roommate whose dog would occasionally clear off the entire coffee table, without any apparent knowledge that anything had happened behind her. Despite debris suddenly flying in most directions from her butt area. I guess that just happens, you know?
It was basically always funny, but we mostly just had drinks and small stuff so nothing too immobile a lot of times the cans would be dented by the tail force.
She was a good dog. My roommate was convinced that she wouldn't get on the furniture, but she was always on something. It's how I knew he'd be home in a minute. She'd get up and he'd walk in. lol
She'd also get on your lap at a glacial pace, over a period of like twenty minutes she would gradually move from floor getting scratches to lap getting scratches.
I have two of those models but apparently their tails are factory reinforced, as every object the tails collide with is either broken or irreversibly damaged. And walls, door and furniture are fun to bang on.
Yeah, years ago I was living in a house with a room mate. behind/below the stairs that ended at the front door was a small hall between a general room and the kitchen. We watched his his sister's dogs for a few days, a great dane and a bernese. Big, but well trained, lovable, lunks.
One day I am on my way home and he calls to ask if I can swing by his work and pick him up. We get home and enter the house. It looked like something out of a horror movie. Large streaks of blood splattered on EVERYTHING. The dogs are already greeting us and seem fine. We see his cat at the top of the stairs, looks just fine. We walk all over the house looking for what the fuck happened. Eventually we have to stop to let the dog out, on their way out the door my room mate noticed the dark gray fur on the dane's tail was matted with something. It was scabbing.
We checked out cameras and he spent almost 3 hours walking back, and forth, through that hall just wailing on the walls with his damned tail. It began bleeding and he was just slinging blood everywhere he went.
I adopted my dog from the local shelter. They had to remove the tip of her tail because she had a happy tail so bad that she had bone deep cuts. They had first tried to stitch the wounds, but she popped the stitches and made the wounds worse. Thankfully, she doesn't have the happy tail affliction anymore. I guess that 'happy' is a misnomer. Her excessive tail wagging was more of a stress/anxiety behavior.
