We live in Winchester, VA and as it has been everywhere recently its been hot as haiti. My dog got fleas and I thought to myself lets go to the vet and they will have the answers and meds. She was already on a medication that stopped fleas and ticks but it ran out and we waited a week to buy the new medicine when it financially benefited us. They gave us the 2nd application which will last for another 6 months we washed everything, washed the dog applied the meds and then the other night I was petting her before bed and noticed she had fleas still. We called the vet and they are so sure they arent fleas but its the exact same thing as before and I know because she is scratching and biting and she never does stuff like that. What are other ways to prevent fleas from latching to my dog??
