Flea Shot For Dogs

There are many safe and effective flea control products for dogs, either available with a veterinarian’s prescription or sold over the counter. Many products kill and prevent other parasites, too, including ticks, heartworms, intestinal parasites, mites, and biting flies. Choosing a safe and effective flea and tick medicine for dogs can be complicated. There are many products available and they’re all a little different. My background taught me a lot about parasite prevention and the various flea control products available today. I spent eight years working as a veterinary assistant in animal hospitals followed by two more decades as an editor for magazines in the pet and veterinary fields. Over the years, I’ve treated countless dogs for fleas, including my own dogs.

Features of Flea Shot For Dogs

A vaccine is a medicine that usually contains antigens of a living organism, mostly a microorganism (e.g. bacteria, viruses, etc.) that is pathogenic for humans or animals (or both). These antigens are administered to the animal that needs protection in order to stimulate its own immune system to produce antibodies against those antigens and this way fight the harmful intruders. In a few cases, the vaccine does not contain antigens, but already antibodies against the harmful intruder. Both antigens and antibodies are mostly very complex proteins that can only be produced by living organisms. This means that they are not at all synthetic chemicals as the vast majority of pesticides and parasiticides.

Numerous human and animal diseases are due to intruding microorganisms such as bacteria and viruses. There are vaccines against many of these microorganisms: e.g. against smallpox, cholera, rabies, tetanus, encephalitis, influenza, etc. Viruses and bacteria are rather simple organisms and it is technically quite easy to produce vaccines against many of them. In fact, >99% of all vaccines available today are against such organisms. However, ticks, fleas, mites, lice, flies, worms and other parasites are multicellular organisms substantially more complex than viruses and bacteria. And it is much more difficult to produce vaccines against them. One of the reasons is that they have found ways to fool the immune system of their host. As already said, there are so far no true vaccines against such parasites for humans or pets, and only very few for livestock.

Flea and Tick Protection for Puppies

Most flea and tick products for puppies are not safe to use until they’ve reached at least seven or eight weeks of age (see chart below). Your veterinarian will be able to recommend a flea and tick preventative for puppies to safely use, and advise you on when it’s safe to begin administering it to your puppy.
