Q. Hi I have a dog that is 3 to 4 month old, he is having attack with vomiting, when he tried to walk he falls and shake like an epilected.
A. It sounds as if he may be having seizures. They can have many causes such as toxins, brain injury, tumor . . . or may be idiopathic--that is, of unknown cause. He needs to be seen at the emergency vet clinic right away. If it continues, and goes into what is called status epilepticus, he may not be able to be saved. I see that he is just a puppy. Be sure that he cannot get into anything poisonous around the house and yard.
