It's generally not recommended to bathe your dog with flea shampoo immediately after applying Frontline. Here's why:
Frontline is a topical flea and tick preventative that works by spreading a thin layer of medication over your dog's skin. Bathing your dog too soon after application can wash away this layer and reduce the effectiveness of the product.
The manufacturer of Frontline recommends waiting at least 48 hours after application before bathing your dog. This allows the product to fully absorb into the skin and start working effectively.
If you need to bathe your dog before the 48-hour mark, it's best to use a mild dog shampoo that's specifically designed for use with topical flea and tick preventatives. Avoid using flea shampoos, as they can strip away the Frontline medication and reduce its effectiveness.
It's also important to note that Frontline is not a substitute for regular bathing. If your dog has a severe flea infestation or skin irritation, your veterinarian may recommend a different treatment plan that includes bathing with a flea shampoo.
