Your Dog's Central Nervous System

The central nervous system (CNS) in dogs is similar to that in humans and other mammals. It consists of the brain and spinal cord and plays a crucial role in regulating the body's functions and behavior.

The CNS is responsible for processing and transmitting information throughout the body. It receives sensory input from the dog's environment and sends motor information to the muscles and organs, allowing the dog to move, perceive its surroundings, and interact with the world.

 

The CNS is also responsible for regulating vital bodily functions, such as breathing, heart rate, and digestion. It controls hormone secretion, body temperature, and immune system responses.

In dogs, as in humans, the CNS is highly sensitive to the effects of medications and toxins. Certain drugs, such as sedatives, anesthetics, and anticonvulsants, can directly affect the CNS and alter the dog's behavior, mood, and physical functions. As we talk about the compounding effects of toxins, emotions, poor nutrition, etc the CNS can be overwhelmed, leading to serious health complications.

Overall, the central nervous system is essential to a dog's health and well-being. It allows the dog to interact with its environment, respond to stimuli, and regulate its bodily functions. Understanding the function of the CNS in dogs is crucial for veterinary medicine and can help prevent and treat neurological disorders and drug toxicity.

 

Fight, Flight or Freeze

The fight, flight, or freeze response is a natural and instinctive response triggered by the central nervous system (CNS) in dogs when they perceive a threat or danger. This response is designed to prepare the dog for survival in potentially life-threatening situations.

When a dog perceives a threat, the CNS activates the sympathetic nervous system, which triggers the release of hormones such as adrenaline and cortisol. This response results in an increase in heart rate, blood pressure, and respiratory rate, as well as a boost in energy and mental alertness.

The fight response is characterized by aggressive behavior, such as barking, growling, and biting, and is often seen in dogs when they feel threatened or cornered.

The flight response is characterized by an attempt to escape the perceived threat. Dogs may try to run away or hide, seeking safety from the perceived danger.

The freeze response is characterized by a lack of movement or response as if the dog has become paralyzed. This response can occur when the dog is overwhelmed or feels unable to fight or flee.

In all three responses, the CNS is responsible for initiating and coordinating the physiological changes necessary for survival. The dog's body prepares itself for immediate action, and the behavior that results is a reflection of the dog's assessment of the perceived threat and its ability to respond.

How Emotions Affect the CNS

Like humans, dogs can experience a wide range of emotions, including anxiety, stress, fear, and trauma. These emotions can have a significant impact on the central nervous system (CNS) and can manifest in both physical and behavioral changes.

When a dog experiences emotions such as anxiety, stress, or fear, the CNS activates the sympathetic nervous system, which triggers the release of hormones such as adrenaline and cortisol. This can result in an increase in heart rate, blood pressure, and respiratory rate, as well as changes in behavior, such as pacing, panting, or hiding.

If a dog experiences a traumatic event, it can lead to long-term changes in the CNS, including alterations in brain chemistry and changes in the way the brain processes information. This can result in behavioral changes such as aggression, fearfulness, or avoidance.

Chronic stress and anxiety can also have a negative impact on a dog's overall health, including the immune system, digestive system, and cardiovascular system. Over time, chronic stress and anxiety can lead to a variety of health problems, including obesity, digestive issues, and heart disease.

It's important to recognize the signs of stress and anxiety in dogs and take steps to manage and reduce these emotions. This may include providing a calm and secure environment, using positive reinforcement training techniques, providing appropriate exercise and mental stimulation, and working with a veterinarian or veterinary behaviorist to develop a treatment plan if necessary. By addressing these emotions, we can help our dogs lead healthier, happier lives.

Recent information from top holistic oncologists even warn us that unaddressed emotions can contribute to cancer and other disease in our pets!

Dysregulation of the Nervous System

When a dog experiences a threat or danger, the sympathetic nervous system triggers the fight, flight, or freeze response, which prepares the body for immediate action. This response is a normal and natural reaction to perceived threats, and it helps the dog to survive in potentially life-threatening situations.

However, if a dog is exposed to chronic stress or trauma, the fight, flight, or freeze response can become dysregulated, and the dog's system can get stuck in one of these responses.

This dysregulation can be caused by a number of factors, including genetics, early life experiences, and chronic exposure to stressors. In some cases, it can be difficult to identify the underlying cause.

When the fight, flight, or freeze response becomes dysregulated, it can lead to a state of sympathetic dominance, where the sympathetic nervous system is constantly activated. This can result in a range of physical and behavioral changes, including an increase in heart rate, blood pressure, and respiratory rate, as well as changes in behavior, such as pacing, panting, or hiding.

In contrast, the parasympathetic nervous system is responsible for rest and digest functions and is activated when the body is in a state of relaxation. When the sympathetic nervous system is dominant, the parasympathetic nervous system is suppressed, which can lead to further health problems.

To help a dog that is stuck in fight, flight, or freeze, it's important to identify the underlying cause and take steps to address it. This may include providing a calm and secure environment, using positive reinforcement training techniques, providing appropriate exercise and mental stimulation, and working with a veterinarian or veterinary behaviorist to develop a treatment plan if necessary. By addressing these issues, we can help our dogs to lead healthier, happier lives.

I find that nutrition, essential oils, herbs, and behavior training help tremendously.
