What is botulism in dogs?

Botulism in dogs is a acute paralyzing disease. This effect occurs due to the action of a neurotoxin, that is, a substance toxic to the central or peripheral nervous system. This particular toxin is produced by the bacteria. Clostridium botulinum, very resistant in the environment.


The dog gets the disease when it consumes decaying meat. This can happen when he eats carrion or if someone inadvertently offers him some meat that has been stored for many days, even if it has been cooked. That's why you should avoid giving leftovers to your dog or, at the very least, not offering them if they've been cooked for several days. Trash and buried food are sources of contamination. That's why botulism is more likely in dogs that live in rural areas or roam alone.

Another way to get botulism is by eating improperly canned vegetables or meat. Finally, it is important to know that botulism in dogs has a incubation period ranging from 12 hours to 6 days.

Botulism symptoms in dogs

Also, you might notice incoordination, weakness or falls. The dog may lie down, with weakness and paralysis in all four limbs and even in the head and neck. He can only move his tail a little, with a feeling of being numb.


In these more serious cases, the dog cannot change position or turn its head. There is a flaccid state widespread. Muscle tone is also diminished. Pupils appear slightly dilated. Paralysis can affect swallowing and therefore you will notice sialorrhea, which is the inability to retain saliva within the mouth, although its production is likely to be affected as well.

Aspiration pneumonia is a complication of this condition. When it is the muscles related to breathing that are damaged, there is an increase in the respiratory rate. The severity of the condition depends on the amount of toxin ingested and the resistance of each dog.
