How to Treat Seizures in Dogs and Cats

What to do if your pet is having a seizure

Seizures stress your pet and your family, but being able to take effective action helps your pet and your family. These are some guidelines:

  • Remain calm and speak to your pet in a soft, comforting voice.
  • Put light pressure on your pet's eyeballs for a minute if it is safe for you to do so.
  • Prevent injury and protect your pet from damaging his or her head by moving objects away from your pet. Do not try to move your pet during a seizure because you may be bitten.
  • Do not approach your pet's head or the mouth because you may be bitten.
  • Do not put medication in your pet's mouth while he or she is having a seizure or unable to swallow.
  • Clean up urine or feces without punishing your pet.
  • Document the event and what led up to the event in a seizure diary.
  • Get emergency help if seizures last more than five minutes or if a second seizure occurs before the brain has completely recovered.
  • Give medications as prescribed by your veterinarian, such as rectal Diazepam.
Place pressure on your pet's eyeballs

Pushing on the eyelids enough to depress the eyeball slightly for 10-60 seconds stimulates the vagus nerve. The vagus increases signals from the calming (parasympathetic) segment of the nervous system and this slows down rapid nerve cell activity characteristic of seizures. If your pet is having a seizure, eyeball pressure helps decrease seizure duration.

Applying eyeball pressure for a minute or two every day before your pet falls to sleep, may help decrease the frequency and severity of seizures. Eyeball pressure also lowers blood pressure.

Treatment options for pets with seizures

Seizures in dogs and cats that occur more often than once a month, occur with ferocity, last for more than 90 seconds, or result in aggressive behavior require treatment.

Treatment for your pet's seizures should include steps that:

  • Strengthen the brain
  • Strengthen the liver
  • Avoid toxins
  • Provide a stable environment
  • Give medication to prevent uncontrolled brain activity
  • Provide surgical relief to brachycephalic dogs
  • Include alternative therapies

When the tendency to develop seizures is inherited, it is best to neuter or spay affected pets.

Recommended products for pets that have seizures (epilepsy)
Strengthen your pet's brain

Supplements that strengthen your pet's brain and build healthy nerve cells and neurotransmitters decrease the likelihood of seizures:

Strengthen your pet's liver

The liver is responsible for removing toxins from the blood. It also controls blood glucose and the amount and type of blood proteins. When your pet's liver is weak and functions poorly, materials enter the bloodstream that can penetrate the blood brain barrier and trigger seizures. To strengthen your pet's liver and keep the blood that circulates through the brain healthy, do the following:

  • Feed no chemicals, fillers, or dyes which the liver will have to process.
  • Provide natural, wholesome pet food.
  • Provide filtered water.
  • Supplement with milk thistle (silymarin or silybum) such as Super VitaChews Soft Chews.
  • Supplement with SAMe, found in Denosyl, to provide antioxidants and liver purifying glutathione.
  • Use homeopathic medications such as Hepar from HeelUSA.
Keep your pet away from toxins

Exposure to poisons or toxins stresses your pet's liver, predisposing him or her to seizures. The following are potential toxin exposures: garages, workshops, bathrooms, new carpets, recently painted walls, recently treated decks, lawns recently treated with fertilizers, herbicides, or pesticides. It can be convenient to put your pet in a garage or bathroom so that he or she does not damage the house or run loose, but this is unwise. Garages, workshops, and bathrooms are full of volatile compounds, such as paints, thinners, and gasoline, cleaners, bleaches, and hair products. Exposures such as these, especially for puppies and kittens, may cause abnormal brain development and lead to seizures. Pets that explore garages, workshops, and bathrooms and then lick their paws or groom themselves inhale and ingest these toxins.

Provide a stable environment for your pet

Most pets with seizures have difficulty adjusting to even small changes in their environment, exercise level, food, or medication. Among the events that can increase the tendency for these pets to have seizures are: changes in the family structure, such as the addition of a baby or another pet, traveling, loud music, loud holiday company, missed meals, late bedtime or changes in sleep cycle, sudden changes in any medication, and changes in the amount of exercise. Exercising pets regularly is part of providing a stable environment, but if your pet has epilepsy, choose activities that are stimulating but non-stressful. For example, tracking may be a better activity than flyball. Many believe that it is not safe to take dogs with epilepsy swimming.

Give your pet medication to prevent seizures

The two most commonly used prescription anti-seizure medications for pets are phenobarbital (PB) and potassium bromide (KBr or K-BroVet Potassium Bromide). Diazepam is not used to prevent seizures in dogs because the effects last about 20 minutes. Cats with epilepsy can be given Diazepam as well as PB and KBr because the effects last 20 hours in cats. Primidone, which is metabolized to phenobarbital in the body, is prescribed for dogs, but many veterinarians do not recommend it for cats. For pets with primary or idiopathic seizures, anticonvulsant medication addresses the problem. For pets with secondary seizures, a group that includes most cats, anticonvulsant medication may resolve the symptoms but it doesn't address the cause. Most pets that start on anti-seizure medications must take them for life.

Effectiveness of BP and KBr

Even when diets, dosages, and all else remains ideal, between 20-30% of dogs are not helped by either PB or KBr.

Side effects of BP, KBr, and Primidone

Unfortunately, PB, KBr, and Primidone and may have serious side effects in your pet: liver damage, drowsiness, weight gain, change in personality, and interfering with bone marrow so that your pet has insufficient infection-fighting white blood cells and blood clotting cells (thrombocytes).

Decreasing the side effects

To decrease the possibility of side effects—which are more severe as the dosage is increased—some veterinarians recommend using smaller amounts of two medications rather than a large amount of one medication. Veterinarians also recommend avoiding toxins and using supplements to support the brain and liver so that medication dosages can be kept to a minimum.

PB, KBr, and Primidone: Slow to act

If your pet is diagnosed with seizures and prescribed these medications, be aware that PB and KBr are slow to become effective. Phenobarbital takes two weeks to reach a steady state and KBr takes three to four months. Periodic blood tests are necessary to measure your pet's blood levels.

KBr and salt intake

For pets on KBr, it's important not to change the amount of salt in the diet. Because KBr is a salt, it competes with normal table salt to remain in the body. If your pet's salt intake suddenly increases because you switch to a different pet food or give salty treats such as hot dogs, luncheon meats, or ham, the kidneys recognize there is sudden increase in salt. To control the salt level, the kidneys eliminate KBr along with sodium chloride. This elimination lowers the therapeutic blood levels of KBr and can lead to seizures.

BP and primidone affect hormones and other medications

Phenobarbital (PB) and Primidone can lower thyroid hormones (T4) and increase thyroid stimulating hormone (TSH), creating hypothyroidism in dogs. In addition to affecting hormones, PB can affect and be affected by other medications. For example, PB decreases the effect of these medications: oral anticoagulants such as warfarin, steroids such as Prednisone, antibiotics Doxycycline and Metronidazole, and the asthma drug Theophylline.

Anti-seizure medications that don't work in pets

Do not be tempted to try Phenytoin, valproic acid, and Carbamazepine. These are effective human anti-seizure medications but they do not work the same in pets as they do in people.

Medications that should never be given to pets with epilepsy

Some medications increase the possibility that pets will have seizures. These prescription medications should not ever be given: Acepromazine, Ketamine, and Xylazine (Rompun).

Which pets should take anti-seizure medication?

Anti-seizure medication is recommended for pets that have more than one seizure every four to six weeks, have cluster seizures, have extremely violent seizures, are less than a year old when seizures begin, have structural problems within the brain causing the seizure (hydrocephalus, cancer), or are aggressive during recovery.

Provide surgical relief to brachycephalic dogs

Surgery helps brachycephalic dogs with short, flat noses so that more oxygen reaches their brains. The surgery shortens the soft palate so that the throat doesn't collapse and widens the tiny nostrils so that more air enters the nose. Among the breeds that may benefit are English Bulldogs, Pugs, Pekingese, Shih Tzus, and Boston Terriers.

Consider alternative therapies for your pet

Holistic veterinarians recommend the following to decrease the severity and frequency of seizures:

  • NaturVet Quiet Moments Calming Aid Plus Melatonin
  • Chinese herbs that improve liver health, such as Tian
  • Ma Gou Teng Yin
  • Gold bead implants at acupuncture points
  • Homeopathic Aconitum 30 C or Cocculus 30 C
  • Magnesium 25 mg/10 pounds body weight for pets with healthy kidneys
  • Vitamin E 25 mg/10 lb
  • Taurine: 60 mg/10 lb
  • Melatonin 1-3 mg at bedtime
Do not attempt to put medication in your pet's mouth during a seizure

It is dangerous for you and your pet to place anything in your pet's mouth during the seizure. Pets having a seizure don't swallow normally and medication put in their mouths can run down into the lungs. It is also dangerous for you, the pet guardian, because your pet may bite during a seizure. Diazepam (Rx) can be given rectally to a seizing pet. Homeopathic medications, such as Aconitum, Cocculus, and Nux Vomica, can be given rectally.

If your pet has gold beads implanted at acupuncture points, they can be massaged during a seizure.

Pets are a lot like people, so keep them healthy as best as you can by following the same advice as you would for a human having a seizure.
