Why is my puppy having seizures?

I have a lab/retriever (he looks like a german shepard) and he's only 6 months old. He's had 3 seizures in the last 34 days. I started giving him phenobarb after the first one for about two weeks and he seemed ok but he's had 2 more since then. I've...

taken him to the vet and called many others and no one can tell me what's wrong. I don't know what to do- he's just a puppy...I've been doing research myself and found that he's having gran mal seizures. it consists of convulsions after he's passed out and fell over on his side not breathing, foaming at the mouth, and running in place or scratching at the floor. It looks so painful and scares me to death! If anyone has advice, iwould greatly appreciate it because I can't seem to get info from any vets- the people who are suppose to help you with your pets...

Well I don't know if this will help but for some reason when you do this it cures most things with dogs. Give them a very small amount of corn syrup. Like coat your finger then feed it to him.

You obviously need to find another Vet.

Seizures are very common in dogs. Idiopathic epilepsy, the single most common canine seizure disorder, is reported to occur in anywhere from 0.5 to 5.7 percent of all dogs.
What is a seizure? Seizure, convulsion, fit, epilepsy. These terms all describe the same thing: What happens when a sudden and uncontrolled burst of neurologic activity occurs in the brain. Sometimes the neurological disturbance remains localized to a small area, such as the face or one limb. Usually, however, the uncontrolled firing of neurons spreads from the brain throughout the body, causing generalized convulsions.
A seizure is not always easy to recognize, and no two look exactly alike. The typical seizure, however, might proceed as follows:
1) The dog becomes nervous or agitated, sensing that something abnormal is about to happen. Some dogs seek out their owners, looking for help and reassurance. This is called the pre-ictal period.

2) The dog begins to tremble. His eyes glaze over and he loses touch with his environment, appears blind, and will not respond to his owner's voice or touch.

3) The trembling becomes more severe and the dog stiffens. He falls, usually on his side, and begins to paddle his legs and convulse, sometimes violently. The teeth might be clenched or the dog may champ his jaws as the seizure progresses. Often, he salivates and appears not to breathe. This entire stage, the ictal stage, usually lasts less than two minutes.

4) The next stage is called the post-ictal period. The dog begins to recover, but a varying degree of neurological signs will persist. Commonly, dogs remain blind for some time after a seizure. They often pant and seem disoriented. Some dogs sleep for a long period following a seizure. The post-ictal stage usually lasts for less than an hour, but can be considerably longer - up to two days.

Did you get your puppy from a pet store? He could be a puppy mill dog and they are usually chock full of genetic problems and health issues like the one you have listed.

In a young dog it maybe epilepsy,but what is called a liver shunt is aslo possible,as well as congenital issues.The puppy should be checked for parasites,and blood tests taken.If nothing shows up you should consider seeing a dog neuologist

At that age epilepsy should be considered,also a condition called a liver shunt is possible,as well as other congenital issues. Check the pup for parasites,and have blood tests taken. Consider a dog neuologist for a consult
