We have been having such a difficult time with ticks this year even though we’ve been using both a topical treatment along with a Seresto Flea collar. Our golden retriever has been on NexGard since the beginning of the month and we are thoroughly pleased with the results, not 1 flea since we started and no itching either. We’ll definitely continue to use both VETRX Direct and NexGard, I highly recommend it.
