Interestingly, tetanus is not common in dogs but it still is a potential danger to our dogs!
If not treated early enough, then complications are likely to occur and in some cases can cause death.
So it becomes really important to know how tetanus affects the dogs, how to distinguish the early signs and what can actually be done about it.
Before we get to the symptoms of tetanus in dogs, causes and treatment let us have a comprehensive view of it.
Understanding Tetanus In Dogs
Tetanus can be defined as a neurological disorder that is caused by the toxin known as tetanospasmin which is produced in the bacterium Clostridium tetani. It is normally a soil-borne bacterium which can penetrate the body of a dog, especially through deep puncture wounds. Inside tissues, the bacteria multiply in areas of low oxygen, and produce a lethal toxin called tetanospasmin.
How Does A Dog Get Tetanus?
Clostridium tetani Bacterium is normally isolated from the dust and soil samples in the environment. Actually, the bacteria in the adult gastrointestinal tract and on the skin are harmless.However, if the bacteria penetrate the body through a deep nick or a cut, more so through puncture wounds then there is trouble because the bacteria thrive well in an anaerobic environment.
Once inside the wound, the bacteria multiply and produce a protein which is the tetanospasmin toxins. Some of the toxins it releases move along the dog’s nervous system and when it gets to the brain and spinal cord it alters the normal functioning of muscles.
Tetanus symptoms usually develop between 5-10 days after the injury although this may take as little as 3 days or as long as 3 weeks.
Recognising Tetanus In Dogs
Tetanus in dogs can be exemplified in two forms: localised and generalised.
1. Localised Tetanus:
This is the more common form in dogs. Symptoms include:
- Stiffness in muscles near the wound site
- Muscle tremors in the affected area
- Difficulty moving the affected limb or body part
2. Generalised Tetanus:
If localised tetanus progresses, it can become generalised, affecting the entire body. Signs include:
- Widespread muscle stiffness
- A characteristic ‘sawhorse’ stance
- Facial muscle spasms, resulting in a ‘sinister smile’
- Difficulty swallowing
- Respiratory distress in severe cases
- Elevated body temperature due to constant muscle contractions
It’s crucial to note that fever in tetanus cases is not due to infection but rather the heat generated by continuous muscle activity.
Diagnosing Tetanus In Dogs
The tetanus in the dogs is mainly suspected clinically when the dog presents with clinical symptoms following a wound infection or injury. There may be a hint in the case of a recent wound, but such wounds can be nearly invisible or very discrete and hidden. Certain tests to check the presence of tetanus toxin or Clostridium tetani are available, yet these are not entirely accurate.
A complete physical checkup by a veterinarian is required. In some cases, the vet may also suggest imaging or other diagnostic tools to rule out other causes of the symptoms.
Treatment Options For Tetanus In Dogs
Early and intensive treatment is required for a good prognosis.
The treatment for tetanus typically involves a combination of therapies:
- Tetanus Antitoxin: Administering antitoxin as early as possible can help neutralise the tetanus toxin circulating in the dog’s body. However, the antitoxin cannot reverse the effects of the toxin already bound to the nervous system, so timing is critical.
- Antibiotics: Antibiotics are used to control the bacterial infection by killing Clostridium tetani. Penicillin is often the antibiotic of choice, but other options may be considered depending on the dog’s condition.
- Wound Care: If the wound that introduced the bacteria is identified, it will require surgical cleaning, known as debridement, to remove infected and necrotic tissue. This helps to reduce the bacterial load and prevent further toxin production.
- Supportive Care: Dogs with tetanus require intensive nursing care. This includes managing muscle spasms, ensuring proper nutrition and hydration, and sometimes providing respiratory support. Dogs may require a ventilator to help them breathe in extreme circumstances.
Prognosis And Recovery
The outlook for dogs with tetanus depends largely on the severity of the condition at the time of presentation. With prompt and appropriate treatment, many dogs begin to show improvement within a week. However, full recovery can take up to a month or longer.
Dogs that present with advanced symptoms or develop secondary complications face a more guarded prognosis. These complications can include:
- Aspiration pneumonia
- Fractures due to severe muscle contractions
- Respiratory failure
Prevention Of Tetanus In Dogs
While there isn’t a routine vaccination for tetanus in dogs, prevention focuses on:
- Prompt and thorough cleaning of any wounds
- Avoiding environments where dogs might sustain puncture wounds
- Regular veterinary check-ups to ensure overall health
It’s particularly important to be vigilant in rural or farm environments where the risk of exposure to C. tetani may be higher.
When To Seek Veterinary Care?
As a pet owner, you should seek immediate veterinary attention if you notice:
- Any signs of muscle stiffness or spasms
- Difficulty eating or swallowing
- Changes in gait or posture
- Any deep or puncture wounds, even if they appear minor
