Intercepter and Sentinel are the same one is without flea medication.

About the dental vaccine for plaque buildup...be careful, someone I know dog had a reaction to it. As far as the heartworm vaccine, it is my understanding it was taken off the market do to it causing death. Revolution works as long as it is applied exactly every 30 days, it doesn't have a grace period like sentinal or intercepter. Sentinal and intercepter as the best as it is based on dog weight. Heartguard is fine but the weight charts are greater, which worries me. You're giving more than is necessary to a smaller dog.
