Did you know, fleas do not stay on your puppy all of their time; occasionally, they will jump off and seek another host. They can infest an entire house. It is important to kill fleas on your new puppy before they can become established in your house. Ask your veterinarian about a good program. Many flea control products that are safe on adult dogs are not safe for puppies less than 4 months of age. Be sure that any flea product you use is labeled safe for puppies. I suggest and use Frontline.If you would rather use flea spray, your puppy should be sprayed lightly. I suggest not to use a flea and tick dip for puppies unless they are at least 4 months of age. It is very important to know that not all insecticides that can be used on adult dogs are safe for puppies.Here is a trick to spraying a puppy that will make the outcome more successful. When a puppy is sprayed, the fleas tend to run away from the insecticide (flea spray). If you spray the body first, this will cause the fleas to run to the head where they are very difficult to kill. The best method to begin first is to spray a cotton ball then use that to wipe the flea spray onto the puppy's face. Begin from the nose to the level of the ears. By using this method it will keep you from getting the medication in the eyes of your puppy and will cause the fleas to run toward the body of your puppy. Wait about 2 minutes or so, then begin to spray the back of the head and the bodyof yor puppy. Leave the spray on for about about 3 minutes, then wipe off the excess. This will kill the most fleas while putting the least amount of insecticide (flea spray) on the puppy.There are usually three products that are given only once per month; these can be used in puppies as young as 6 weeks. Program( is a tablet that causes the adult fleas to lay sterile eggs. It is very effective, but Program does not kill adult fleas that usually live 2-3 months, meanhile they can infest your home. Advantage and Frontline are monthly products that kill adult fleas and ticks. They are liquids that are applied to the skin at the base of the neck. They are very effective and easy to use. I suggest and use Frontline. These products can be found through your vet clinic.
