Why does Frontline only work sometimes on fleas? Do I need to try something else?

I've been using Frontline to treat our dog for fleas, and I've noticed that it seems to work well sometimes, but not always. After a recent application, she was still scratching quite a bit, as if the fleas weren’t all gone. Could it be that the fleas in our area have become resistant, or should I consider an alternative treatment or even a combination approach to keep her comfortable and flea-free?

Answer

Your concern about flea treatment effectiveness is valid. While Frontline is often effective, there are instances where it might not fully address the issue.

  • Monitor your dog's scratching and flea activity post-treatment.
  • Consider environmental factors that may reduce treatment efficacy.
  • Evaluate the possibility of resistance or an alternative treatment plan.

It's possible that fleas in certain areas may develop resistance to certain treatments over time, including Frontline. Additionally, environmental factors such as other untreated animals or flea-infested spaces could be reintroducing fleas. Consider trying a different product or a combination approach, such as using a flea comb in conjunction with treatment, to help your dog achieve relief.
