Is there a disease that makes dogs aggressive

On the warm days spent with dogs, they are often the little suns in our lives, illuminating our lives with liveliness and loyalty. However, when dogs suddenly show aggression, it not only scares those around them, but also pains and confuses us as dog owners. Many people may wonder if there are any diseases that can quietly change a dog's gentle temperament and make them more aggressive?

Neurological disorders have a significant impact on the behavior of dogs. Brain tumors are one of the more serious cases. As the tumor grows in the dog's brain, it gradually compresses the surrounding nerve tissue and interferes with the normal transmission of nerve signals. This is like mixing impurities into a precise circuit, causing the entire system to malfunction. Dogs that were originally gentle and obedient may experience a significant change in their temperament, becoming irritable and restless, and becoming aggressive towards people and other animals around them. For example, when a dog's temporal lobe is compressed by a tumor, it may trigger epileptic seizures. During the period before and after the seizure, the dog may exhibit abnormal behavior, and aggressive behavior is one of them. It may rush towards its owner or other animals without warning, with unfamiliar ferocity in its eyes, shocking those familiar with it.

Epilepsy is also a common neurological disorder that can cause aggressive behavior in dogs. During a seizure, the dog's brain will experience abnormal electrical activity, which not only triggers seizures but also has a profound impact on the dog's emotions and cognition. Before a seizure, dogs may exhibit feelings of unease and anxiety, which can transform into aggression during the seizure. After the attack, the dog may be in a confused and uncomfortable state, overly sensitive to surrounding stimuli, and even a slight movement may trigger its aggressive behavior. Imagine a dog, after a seizure, whose body has not fully recovered yet. The approach of people around it and the stimulation of sounds may make it unable to withstand and launch attacks. It is not intentionally harming, but rather unable to control its behavior due to the disease.

Neurodegenerative diseases should not be underestimated. This type of disease will gradually erode the nervous system function of dogs over time. Taking canine cognitive dysfunction syndrome as an example, it is similar to human Alzheimer's disease. Dogs with illnesses may experience symptoms such as memory loss and disorientation, and their emotions may also become extremely unstable. Due to confusion in understanding the surrounding environment, dogs may develop aggression due to fear and anxiety.

Hyperfunction of the adrenal cortex can also have an impact on the behavior of dogs. Dogs with illnesses have elevated levels of cortisol in their bodies, which can affect their emotions and behavior. Cortisol is a stress hormone, and prolonged high levels can make dogs more irritable and aggressive. At the same time, hyperfunction of the adrenal cortex may also lead to other physical symptoms in dogs, such as excessive drinking, frequent urination, and abdominal swelling. These physical discomforts can further exacerbate the dog's irritability and make it more prone to aggressive behavior.

Pain is also an important factor that triggers aggression in dogs. When dogs suffer from severe arthritis, the pain in their joints can torment them with every movement. Under this persistent pain, dogs' emotions become extremely unstable and they become extremely sensitive to surrounding stimuli. The gentle touch of the owner or the approach of other animals may be seen by dogs as a threat to their painful areas, leading to aggressive behavior. Fractures, oral diseases, and other conditions can also cause unbearable pain to dogs, making them irritable and aggressive in the midst of the pain. For example, if a dog suffers from periodontitis, the pain in its teeth can make it uncomfortable while eating or playing. When someone tries to approach its mouth or other animals accidentally touch its face, it may attack out of pain and self-protection.

When we notice aggressive changes in dogs, our hearts are often filled with worry and self blame. But at this moment, it is crucial to remain calm and take timely action. Firstly, it is necessary to take the dog to a veterinarian as soon as possible for a comprehensive physical examination and neurological assessment. Veterinarians will use detailed consultations and professional examination methods, such as blood tests, brain imaging examinations, etc., to determine whether dogs have diseases that cause aggression. If it is caused by a disease, veterinarians will develop corresponding treatment plans based on the specific condition, such as medication treatment, surgical treatment, etc. During the treatment process, the owner should give the dog enough care and patience to accompany it through the difficult treatment period.
