After being gone from home, one of the things that gives me great joy is seeing how hard my dog wags his tail when he sees me Why do dogs wag tailagain. It always makes me feel like he is so happy to see me.

I have been lucky with the dogs that I have owned, since all of them have an over exaggerated tail wag when they are happy, from it almost knocking them off their feet to them thumping their tail on the floor sounding like they are beating a drum.

So why do dogs wag tails? It isn’t always because they are happy to see you. That is why you need to be able to read your dog and the signs of other dogs to know which dogs are approachable and which ones you should back away from.

Dogs use their tails as a way of communicating to people and other dogs. If you don’t know the dog, but they are wagging their tails, you need to look for other body language to determine if they are friendly or not. Pinned back ears or a rigid body are signals that the dog wagging his tail at you isn’t doing it because they are glad to see you.

A dog wagging his tail is telling you he is happy to see you, he is afraid of you, he is in charge, or maybe he doesn’t like you. You need to understand what type of tail wag they are giving you, so you understand if you can pet them or if you need to back away.

Why do dogs wag tails can change for different situations.  It is good for you to understand what does the tail wag mean and the different types of tail wags you might see from dogs

Generally, most dog owners have a pretty good understanding of how their dog is feeling about a certain situation, but you should learn where your dog carries his tail when he is feeling relaxed or happy. That will help you be aware when you dog meets other people or dogs if he is feeling stressed, agitated, or afraid. It will help you prevent any unwanted behavior from your dog by removing him from the situation.

You also need to be aware of other dogs that you are meeting. If you are a dog lover and you see a dog you want to go up and pet, I suggest first asking the pet owner if it is OK, since they will know their dog’s disposition and if their dog is friendly to strangers. Just because you see a dog wagging his tail doesn’t mean that dog wants you do come up and pet them. Watch for the other signals the dog is giving off, and watch for the tail position and the type of tail wagging he is doing.

It is better to be safe, than just reaching out to pet an unknown dog. You don’t know why that dog is wagging his tail.

  1. Hi Marla,

    I love this post, dogs are so loving and give their all to us.
    Throughout our 51 year marriage, my wife and I have had 5 dogs, such great companions, our last dog, a white German Shepherd died last year and sadly, I don’t think we will own another dog as, since a fall, my wife is now disabled and I now care for her.

    • Ken, I’m glad you read my article. Five dogs is great, but I am sorry that you lost your last one last year. That is really hard. I am also sorry you won’t be getting another one. They are such great companions, but maybe you can friend a neighbor’s dog.

  2. Hey Marla thank you for this, I’ve always had that uneasy feeling when a dog I don’t know wags their tail at me! Now I have a better understanding of what to look for before freaking out hehehe. Side note for lols – I was chased by a huger than huge great dane as a kid – it was scary as hell.

    • Nadia, I’m glad this will help you be more at ease when you see a dog wagging his tail to know if you should approach him or not. I have found that most dogs are friendly, but every once in a while that is not the case and you need to be careful. I am sorry you got chased by a dog when you were young. That can really stick with you.
