The tooth may die and it is possible that an abscess may develop which could be treated conservatively with antibiotics. Our 6 year old male Labrador has started having seizures. They occur infrequestly, about once a month. He does not lose control of his bowels, but occasionally dribbles some urine. The vet wantes to put him on phenobarbital, but we are reluctant to use such a strong drug on a relatively young dog with infrequent seizures.
Some dogs do well on potassium bromide or primidone.
I've heard some success with a high fat diet, making one-third of your dog's daily ration very high fat hamburger lightly cooked. Other dogs seem to do better on a natural whole food, organic diet that you make up yourself. You should avoid subjecting your dog to conditions that may cause stress, overexcitement, and also think twice about having him given booster vaccinations. My 11 year old male cat has hyperthyroidism. I can't get him to swallow a Tapazole pill every day.
