Frontline Plus is generally safe for use on puppies that are at least 8 weeks old and weigh at least 5 pounds (2.3 kilograms). It's essential to use the correct dosage based on your puppy's weight and to follow the manufacturer's instructions carefully.
Puppies younger than 8 weeks old are too young for most flea and tick treatments, including Frontline Plus. At such a young age, their bodies are still developing, and they may not tolerate the active ingredients in these products well.
Before using any flea and tick product on your puppy, it's always a good idea to consult with your veterinarian. Your vet can provide guidance on the most appropriate flea and tick control options for your puppy's age, weight, and overall health status.
Additionally, always monitor your puppy closely after applying Frontline Plus or any other flea and tick treatment for any signs of adverse reactions or discomfort. If you notice any unusual symptoms or behaviors, contact your veterinarian for further advice.
