However, there are a few considerations to keep in mind. This shampoo is not suitable for pets younger than 12 weeks, and it requires a thorough application and rinsing process that might be time-consuming.

While it is effective, users need to repeat the application every 7 to 10 days for adult flea relief, which might be cumbersome for some.
