Snakebite Signs & Symptoms

Posted July 24, 2026 in General

Signs and symptoms of a snakebite in a dog can be tricky for a number of reasons. Not every dog will react the same way, or react the same way the next time they are bitten (which hopefully they are not!). There is no singular key sign or combination of symptoms that indicate that there is 100% a snakebite, and a number of the symptoms are the same as those caused by other toxins such as chocolate, grapes etc.

So what should you be looking for? Signs & symptoms of a snakebite may include:

–              Vomiting

–              Excessive salivation, drooling, or frothing at the mouth

–              Respiratory distress

–              Muscle weakness and difficulty blinking

–              Full or partial paralysis

–              Blood in the urine

–              Loss of bladder and/or bowel control

–              Sudden weakness followed by collapse

–              Dilated pupils

But how do you know if it is a snakebite? Unless you see the snake biting the dog, the only way to truly diagnose a snakebite is through a blood test by a vet. Though the above signs are generally points of concern for many owners in any situation, and it is recommended to seek prompt veterinary attention, this is especially true if you have seen a snake nearby or your dog has been out in a “snakey area” (i.e. bushland or sand dunes). 

If you are worried that your dog may have been bitten by a snake, always seek immediate veterinary attention!
