Rabies vaccination makes a dog ferocious!!!

Rabies Miasm

This is a condition in which the dog behaviour after rabies vaccine mirrors the symptoms of having contracted rabies.

There are particular dog behavioural changes after rabies shot that stand out and should be a cause for concern with any dog owner. Behavioral reactions to the rabies shot may vary between aggressive behaviour towards both humans and animals, suspicious behaviour, a lack of affection, confusion, separation anxiety, a lot of barking bordering on excessive, tail chewing and destructive behaviour


Rabies vaccine can be harmful to your dog!!!

Most conventional vets will tell you that rabies vaccination is very safe and unlikely to
cause any side effects.

Acute Problems

Acute reactions can happen immediately after the rabies vaccine or within a few days. Conventional vets are more likely to recognize acute (vs chronic) reactions as being linked to the rabies vaccine.

These acute reactions aren’t necessarily limited to the rabies vaccine but can happen with any shots.

  • Vomiting
  • Facial swelling.
  • Injection site swelling or lump.
  • Lethargy.
  • Urticaria (hives).
  • Circulatory shock.
  • Injection site pain.
  • Pruritus (itching).
  • Injection site alopecia (hair loss).
  • Death.
  • Loss of consciousness.
  • Diarrhea.
  • Hypersensitivity.
  • Fever.
  • Anaphylaxis (which can kill your dog in minutes).
  • Ataxia (loss of balance/coordination).
  • Lameness
  • General signs of pain.
  • Hyperactivity.
  • Injection site scab or crust.
  • Muscle tremor.
  • Seizures (these can be immediate upon vaccination but can also occur in 7 to 9 days which is when the rabies antibodies develop).
  • Tumor at the injection site (this can happen within as little as 72 hours).
  • Sudden behaviour changes such as aggression, fear or anxiety can also happen acutely, within hours or days of rabies vaccination.
  • Immune-mediated hemolytic anaemia (IMHA). This disease can also become chronic.

Chronic Problems

Many chronic diseases in dogs can be triggered by the rabies vaccine’s damaging effect on your dog’s immune system and neurological system. The rabies virus itself is a carcinogen. The toxic ingredients in vaccines such as aluminium and mercury can also contribute to cancer and another chronic disease. 

    • Fibrocarcinomas at the injection site. A lot of people know about this problem in cats (that’s why vets often vaccinate cats in the tail, so it can easily be amputated) but it’s just as common in dogs. Fibrocarcinomas can appear in places other than the injection site because the aluminum in the vaccine is carried away by macrophages (immune system cells that detect, eat and destroy damaged cells and other foreign substances).
    • Other cancers, such as spindle cell cancers, mast cell cancers, hemangiosarcoma, osteosarcoma, lymphoma. Even benign tumors like lipomas, warts and other growths can grow larger or become malignant after rabies vaccination, especially if your dog is taking steroid drugs.
    • Chronic digestive issues such as Inflammatory Bowel Disease, colitis or chronic diarrhea. Inflammation anywhere in the body, including in the digestive tract, is aggravated by the rabies vaccine.
    • Seizures, epilepsy and granulomatuous meningioencephalitis (GME).
    • Food, environmental and inhalant allergies. These are extremely common chronic problems in dogs. Allergies are improper immune responses and vaccination can damage your dog’s immune system. The aluminum in vaccines also causes an up-regulation of IgE, which is the allergy immunoglobulin.
    • Skin issues. There are many different types of skin issues, including dermatitis, yeast, alopecia (hair loss), hives, rashes, itchy wrists and ankles (where a lot of dogs chew themselves), abscesses, ear and eye infections and anal gland problems. Skin conditions are never “just skin issues” but are a manifestation of deeper underlying disease. Vaccination can cause allergic reactions because cells in the body called Langerhan cells are constantly scouting for antigen (which the rabies virus is full of). When Langerhan cells detect these foreign invaders (like bacteria or viruses), the body then sends out inflammatory cells to fight off the attacker by creating an allergic reaction.




  • Muscle weakness or atrophy, including wasting diseases like degenerative myelopathy and Guillain Barré The rabies vaccine causes a neuro-inflammatory reaction, resulting in degeneration of the tissues.
  • Demyelination (common in German Shepherds) – an autoimmune disease.
  • Autoimmune diseases such as rheumatoid arthritis, lupus, autoimmune thyroiditis.
  • Metabolic diseases like diabetes, Cushing’s disease, Addison’s disease or pancreatitis.
