Your dog is just like you, he has his good days and bad days. Dogs get easily affected by things around them just like us. Your dog might be in a god mood or bad mood. And your dog’s mood depends on the environment he is in. Determining your dog’s temperament is not a tough nut to crack.
Looking for the tell tale signs
If your dog is happy, then he wags his tails, bounces around the house and has a happy demeanor around him. Some dogs when very excited tend to run around happily and bark. But if your dog is sad then he stoops low on the ground and doesn’t interact with you. Pat him and cuddle him to uplift his mood. Lastly if your dog is angry then he is growling continuously and seems as if he is very alert.
