Questions & Answers

1 Customer Questions

Is this product safe for dogs (4) that play around and nibble at each other? what I mean is it safe if they put their mouths on the application area of the other dogs?

Answer by Chewy • Mar 31, 2022
Do not allow the dogs to play with each other until the treatment has fully dried and been absorbed, which generally takes 24 hours.

Do not use

Negative medical reactions and emergency vet trip ensued after application with our cat, so I never used on my dog. Threw it away.

This used to work so well. But this year is the worst. I don’t know if they changed the ingredients but it didn’t work for our dogs. We would see ticks falling off

This used to work so well. But this year is the worst. I don’t know if they changed the ingredients but it didn’t work for our dogs. We would see ticks falling off of them and we would spend a lot of time picking ticks off too. Today they went to the vet. The duds had so many ticks and I was embarrassed. We had to shave our dogs and when we got home, we still found more ticks on them! Don’t buy it! Our dogs are being treated with Lyme and another disease caused by ticks.
