My vet told me that the revolution does not protect against deer tick that cause lyme disease, but he said since they was inside dogs that should be ok. I did not put my outside dogs on revolution because they go into the woods and the creek. He said that revolution protected against intestinal worms too, except for whip worms. I only started using it this month so I don't know how well it works yet, but I have not seen any fleas or ticks on Hannah and Bentley and they play outside in the yard alot. |
