Why Has My Dog’s Personality And Temperament Changed?

There are many things that can lead to behavior or personality change within your dog. Below, we will discuss some of the common things that can lead to behavior change and some ways that you can get your dog back to its old self again.

Anxiety and Stress

Dogs can become stressed just like people. We want to make sure our pets have a good environment that is stress-free and positive for their health. Dogs communicate with their owners and human counterparts through body language and warning signs. There are a number of stress indicators, including growling, barking, and pacing.

To keep your dog happy and healthy, you should know the common causes of stress and the warnings of stress in your dog. We will cover some indicators of stress in your dog, along with some methods you can use to help him relieve the stress.

It is always best to have your dog seen by the vet first if you notice a change in its behavior. The vet can make sure that your dog is in optimal health by looking at any underlying medical issues. They can give you tips to help lower your dog’s stress level and ward off bad behavior. 

Mental Stimulation and Exercise: It is important to give your dog plenty of mental exercise and physical stimulation to keep him in great physical health. Reducing stress in dogs and people can be accomplished through physical activity. You can either play a game of fetch with your dog or walk around the block to increase your dog’s activity level.

Create an Escape Zone: Your dog needs an area that it can retreat to if it is feeling anxious or stressed. This area needs to be set apart from the rest of your home or apartment to provide your dog with an escape. You can put your favorite toys and blankets in this area to make your dog more secure. You should sit with your dog to calm him down if he retreats to this space because of loud noises. Your presence will make your dog think everything’s okay.

Health Issues


Rabies is a deadly viral disease that affects many different animals. Rabbies is a member of the zoonotic disease family, meaning it can also affect people.

Sadly, rabies is not curable, and it rapidly affects the brain, spinal cord, and nervous systems of the infected wild animal. While the fatal virus is preventable and treatable if discovered early on, once symptoms appear, there is nothing you can do to help your dog, and there are no treatment options. This is why it is extremely important to ensure that your dog is current on all of its vaccinations.

The virus is transmitted through the saliva of the infected wild animal, typically through being bit by the animal. However, it is also possible that it is spread through the direct contact of the saliva with mucous membranes or superficial wounds. The virus advances to the central nervous system and salivary glands from the entry point and is distributed throughout the dog’s body. 

This virus leads to drastic behavioral changes in dogs and can quickly lead to aggression, undesirable behavior, and sudden death. 


Canine distemper virus is part of the paramyxoviruses family and can spread very rapidly. It is transmitted by contact with various secretions from an infected animal such as saliva, urine, and feces of sick animals by inhalation, oral ingestion, or contact with the fetus with viruses through the mother. In the latter case, the disease only manifests itself after weaning the puppy as the puppy does not have maternal protective proteins (antibodies) anymore. 

The distemper virus in dogs is very contagious and spreads quickly. This disease is also incredibly lethal among dogs. However, the good news is that it is preventable with proper vaccinations and regular veterinary checkups.

The virus attacks certain cells of the immune system. Normally, they are tasked with detecting, absorbing, and then killing pathogens such as bacteria and viruses. However, distemper viruses can survive in macrophages and even multiply enough in them not to be destroyed. After just a few hours, they reach the lymph nodes and other lymphatic organs such as the spleen and liver through the lymph. In a short time, viruses reach the entire body through the bloodstream. The main targets are the urinary, genital, and respiratory tracts and nervous tissue.

This virus can cause behavior change within your dog due to the pain it causes to the canine. As a responsible pet owner, you should ensure that your canine companion receives all of the proper vaccinations and veterinary visits to prevent them from suffering from this disease. 

Spaying or Neutering

Spaying and neutering can have an effect on a dog’s undesirable behaviors. The removal of the reproductive organs brings changes in the body and directly influences the mind and social behavior. It is especially those who have a male at home who opt for castration as a last resort to aggressive and restless behaviors caused by testosterone.

A castrated male is calmer when confronted with a female dog in heat. Also, competitive sexual behavior with other males is no longer a problem as this normal behavior disappears. Howling, barking, and attempts to escape driven by sexual desire does not occur when the dog has been neutered.

However, castration does not change other aggressive type behaviors. It only changes behaviors related to sex hormones. Aggressive behaviors are the result of errors in education and a lack of training in regard to behavior modification. 


Pyometra, or Cystic Endometrial Hyperplasia, is a prevalent hormonal disease in female dogs caused by an abnormal increase in the progesterone hormone. This disease can lead to behavior issues.

Over time, dogs with pyometra can end up having issues with fertility and pregnancy. In more severe cases, the female dog can even suffer organ failure and death. This can happen if we neglect to receive proper care for our dog or because of the dog’s genetic misfortune. So, it is crucial that we get involved in proper treatment in order to avoid early death or adverse health effects.

Although you should not be too worried about canine pyometra, it is important to deal with the disease if you do not want to cause long-term health issues within your dog. In fact, a large portion of female dogs ends up going through canine pyometra sometime in their lives.

Scientists have discovered that the hormonal cycle is closely related to the contraction of the disease; putting female dogs at a much higher risk of pyometra at certain times in their heat cycle. It usually appears about ten or twelve weeks after ovulation in their heat cycle.

It is usually due to a natural increase in the hormone progesterone. This causes uterine contractions to decrease and end up generating some related changes in the endometrium. In summary, canine pyometra is a prevalent uterine infection in the canine world that only affects female dogs once they have reached sexual maturity. It is considered a secondary infection and does not have the capacity to be contagious.
