My vet recommends that to protect my dog from both fleas/ticks and lungworm that we alternate monthly treatments of Advantix and Advocate as there is apparently no preventative treatment that covers all these parasites. Is this really true?
We've been doing this for a while and it seems ineffective for ticks over an 8 week period, so I'm worried that it's not effective for lungworm either. He generally picks up a few ticks in the second half of the month that he has Advocate. We walk a lot in woods (lots of ticks) but I have never ever seen him eat a slug or snail. I apply the spot-on stuff very carefully exactly according to the instructions.
Would really appreciate other people's experience/advice.
