1. Reduced Effectiveness: Applying flea medication to a wet or damp coat can dilute or wash away the active ingredients. This can make the medication less effective in killing fleas and preventing future infestations.
2. Skin Irritation: Flea medications are typically applied topically to the skin. Applying it to skin that is already wet or softened from bathing may increase the risk of skin irritation, redness, or discomfort for your dog.
3. Absorption Issues: The skin's ability to absorb the medication may be affected if it is applied to wet fur. This can prevent the medication from reaching its full potential in protecting your dog against fleas.
It's generally advisable to wait for your dog's coat to dry thoroughly after bathing before applying flea medication. This allows the medication to be applied effectively and reduces the risk of potential issues. Always follow the instructions provided on the flea medication packaging and consult with your veterinarian if you have specific concerns or questions.
