## Questions & Answers

**Q: Will it stay on if you give the dog a bath?**
A: The directions states that its waterproof after applying it on the dog. But, I feel it would remain more effective if you tried tp avoid a bath as I believe it weakens the protection. But either way is okay.

**Q: How many applications come in each box?**
A: It says on the front of the box. 3 or 6 depending on which one you buy.

VetOne - CrossBlock II was recommended by our vet. We've been using this brand for years. It works well and we haven't had any troubles or infestations since we've been using it. I would recommend CrossBlock.

    Best on the market
  

*by J***Y on Reviewed in the United States on October 10, 2020*

Better then Frontline and every single thing out there. I was going broke trying to find a solution to the flea problems I decided to try this and three years later I put a dose on when I see the first flea and instantly fleas jump off him or die I love it and 4 times cheaper then Frontline and all the major brands. Hands down the best ever. I will continue to use this brand. It seems fleas are getting use to Frontline etc. But 4 years later using crossblock it now fleas instantly. I'm so glad I tried this brand. Thank you crossblock
