Despite being the world smallest dog breed, chihuahua are prone to suffer from seizures as well. Here are a few common causes for seizures in chihuahua.
Epilepsy is one of the better known hereditary health conditions that can be found within the Chihuahua breed, and this is perhaps the most common cause of seizures within dogs of the breed too. Epilepsy is a type of seizure disorder that may result in very obvious grand mal seizures, or more subtle and easy to miss petit mal seizures, which usually pass within just a few seconds and often simply look as if the dog has zoned out for a short while.
Epilepsy in dogs cannot be cured, but it can usually be managed effectively with the appropriate medications, which your vet will prescribe once they reach a diagnosis and begin to advise you on your dog’s future care.
Hypoglycaemia means low blood sugar, and this is what sometimes causes us to feel weak or shaky if we don’t eat at the usual time our bodies expect us to. Hypoglycaemia is another health condition that is found more commonly within dogs of the Chihuahua breed than most others, and this pertains to the dog’s small size.
Because the Chihuahua is so small, their blood/sugar balance is much more delicate and with less margin for error than it is in larger dogs, and more prone to falling out of whack. Chihuahuas need to be fed little and often in order to maintain a healthy blood/sugar balance, and being late with a meal or providing the wrong quantity of food can all affect the levels of glucose in their blood.
Hypoglycaemia can result in hypoglycaemic seizures, although these don’t tend to happen unless the dog’s blood/sugar balance is very off kilter. Again, talk to your vet if you have any concerns or if you need advice on the best way to feed your Chihuahua.
Hydrocephalus or fluid on the brain occurs more commonly in the Chihuahua than most other breeds, and is often associated with the large, dome-shaped skulls that they have. Hydrocephalus places pressure on the dog’s brain and can lead to seizures and a range of other symptoms, and the condition can be life-threatening for your dog if it is not promptly treated if it does place undue pressure on their brain and nerves.
Generally, hydrocephalus in the Chihuahua will be diagnosed while the dog is still young, and it doesn’t always cause problems like seizures – but problems can develop later on in life, and so this is always something that is worth bearing in mind.
Finally, poisoning or toxicity of many different types can result in seizures in dogs, and this is not exclusive to dogs of the Chihuahua breed. However, as we alluded to earlier on, the amount of any poison or toxic substance required to cause harm to a dog depends in part on the dog’s size, so if your Chihuahua eats something they shouldn’t eat or is otherwise exposed to a toxin, they are likely to become sicker than a larger dog would.
Poisoning with many different toxins can result in seizures, and such symptoms usually develop quickly and are often quite acute. Contact your vet as a matter of urgency if you think your dog has been poisoned or eaten something toxic, even if they appear to be perfectly fine at the time.
