    Frontline is a very effective monthly flea control drug that is used to successfully treat dogs for flea infestations as well as prevent future infestations. Frontline has been shown to be extremely effective and safe in most applications including use in very young puppies. The first thing you should do is to determine why the application of the medication failed. The reason for this is so that you can avoid making the same mistake in your application when re-dosing your puppy. Make sure that the dosage you are using commensurate with the proper dose recommended by the manufacturer for the weight of your puppy. Using too little product will lessen the product's effectiveness. Next, do not bathe your puppy immediate before the application of the product or immediately after. The reason for this is that Frontline utilizes the natural oils found on your dog's skin to distribute itself. If these oils are missing due to bathing, or if you bathe the dog before it has the opportunity to distribute into the hair follicles, the product will not work properly. You should bathe the puppy at least 24 hours before the application of the product or wait at least 24 hours after the application of the product before bathing. Also, understand that there is a distinct possibility that the product is working as it should and what you are seeing is fleas that are attempting to infest the puppy from the environment. If the puppy was infested with fleas prior to the application of Frontline, there is a distinct possibility that there is also a flea infestation of his bedding, your carpet, or yard as well as eggs that have yet to hatch. Take measures to treat these areas and take comfort in knowing that the medication will continue to kill the fleas that are infesting your puppy for up to one month, making your puppy a very effective flea killing machine. Frontline is designed to be applied every 30 days. Since your puppy is very young, it is not advisable to reapply the product to your dog until the next scheduled dosing interval, which will be 30 days after the initial dose. If you are concerned about residual fleas on your puppy, visit your veterinarian who may be able to give you additional suggestions for helping reduce the number of fleas on your puppy until the Frontline product has gotten them under control.

  • Concern on using topical flea control for a child's service dog

    Concern for use of topical flea control for a child's service dog I have a child with a service dog for seizure alert and she is very delayed-she is constantly putting her hands into her mouth. I am considering switching flea and heart worm medication (we currently use Sentinel) however am very concerned about the use of topical spot treatments for fleas as my child will handle the service dog then put her hands into her mouth. They obviously can't be separated to allow the topical to fade from the fur and you can't bathe a dog right after application. Am I over-reacting to using a topical or do I have valid reason to be concerned?

    Staph Infection Our dog has a half dollar size wound on his throat - the fur is gone - a little bleeding. 24 hrs after we noticed the wound, we went to the vet. Vet thinks that it could have been a bug bite that he kept itching? Vet said that it looked like it was or would become infected (staph) so she gave us antibiotics. We have an infant and I'm concerned that the dog could pass the staph infection to our baby. The vet said no, but I've looked online & seen where others say it can. What do you think?

  • My dog has a sudden behavioral change... Is she ok?

    My vet said I could give my dog frontline after 21 days, because I've seen a few fleas on her in the last couple of weeks. A few hours after I applied the frontline, around bedtime, she was acting really strange hiding in the kitchen in the dark, running into rooms she never does, hiding in the closet refusing to be touched. Gave her a bath and today seemed normal til we got back from our evening walk (where she played & ran as usual) and then repeated behavior like last night. Is she ok?

  • Can dogs treated with Frontline still get Lyme disease if bitten by a tick?

    I have a 3yr old mixed breed that has been on Frontline since she was a puppy. She has never had any ticks on her, but I am planning on taking her camping this fall. From what I understand Frontline doesn't prevent tick bites, it just kills the tick. So is it possible for her to contract Lyme disease if she is bitten even if the tick doesn't remain on her? If so is there anything else I can do besides checking her for ticks right after hiking? Thanks for your help.

There has been no puss from it and it doesn't seem to bother him. We are trying to get him into the vet but it's taking some time.
