Advocate is a flea and lung worm treatment to be used monthly, every month.
Frontline is a flea and ticks treatment to be used monthly, every month.
My vet recommended Advocate, saying the lung worm is a life threatening illness. But Millie got a tick the although discovered very quickly, required anti biotics.
I decided to swap to Frontline as Millie is a fan of running through long grass and the risk of ticks is high. I don't want her having to have loads of antibiotics from tick infections.
The vet wants me to use Frontline and then two weeks later Advocate !.. Rightly or wrongly I feel this is just too much. I'll stick with Frontline for late spring to autumn whien ticks are around and I may swap back to Advocate for the winter months.
Unfortunately, there isn't a flea treatment that covers everything.
