Here's why:
* Dosage and Frequency: The appropriate treatment frequency depends on factors like your dog's age, weight, breed, and the severity of the infestation. A veterinarian can assess your dog's individual needs and prescribe the correct treatment plan.
* Safety: Over-treating can lead to health problems and potentially even toxicity. Veterinarians are trained to understand the risks and benefits of different flea medications and will ensure your dog receives the safest and most effective treatment.
* Resistance: Using treatments too frequently can contribute to flea resistance, making it more difficult to control infestations in the future.
It's always best to err on the side of caution and follow your veterinarian's advice.
They can help you choose the right flea treatment for your dog, determine the proper application frequency, and provide guidance on preventing future infestations.
