    Are fleas dangerous or harmful to pets or humans?

    If your dog, cat, or other pet has fleas, can they be harmful to humans?  I understand they're a pest and cause bites, but what other dangers do they pose?

    If your pet gets fleas..the chances that he will get or have worms..which can be dangerous as pets health will deteriorate...Fleas can also be harmful to humans, as the bites can become infected, causing health problems...there are many products on the market today that can prevent fleas becoming an issue...take precautions year round....

    The flea that likes dogs and cats is not going to drink blood from a human unless he is really hungry and has no other source. (Thus, you can lay down with dogs and not get fleas.) The type of intestinal parasite dogs get through eating fleas does not cause health problems to the dog, although they are quite ugly!
    The biggest health problem I know of is flea allergy dermatitis, and dogs only develop this problem after the fleas have bitten many times, enough so that the dog has an allergy to the flea saliva. I have never heard of this happening to a human, although it is not impossible.

    Fleas are host specific and may not necessarily harm humans, although its important that you eliminate them since they can be aberrant parasites to humans.

    It would be a grave mistake to think of the flea as simply a nuisance.  A heavy flea burden is lethal, especially to smaller or younger animals. The cat flea is not at all selective about its host and has been known to kill dairy calves through heavy infestation.  Conditions brought about via flea infestation include:

    Flea Allergic Dermatitis
    (remember, fleas do not make animals itchy unless there a flea bite allergy)
    Flea Anemia
    Feline Infectious Anemia
    (a life-threatening blood parasite carried by fleas)
    Cat Scratch Fever
    (does not make the cat sick but the infected cat can make a person sick)
    Common Tapeworm infection
    (not harmful but cosmetically unappealing)
    Are you protecting your pets from fleas ticks and chemicals ?


    Pet Protector disc can be used from the first day of your pet's life.

    It's important for pet owners WHO USE CHEMICAL PRODUCTS to read the label and follow the directions carefully. If the label states that the product is for animals of a certain age or older, don't use the product on pets that are younger. Puppies and kittens are usually too young for chemical products against fleas and ticks.

    Pet Protector is non-toxic and contains no chemical elements; THEREFORE IS COMPLETELY SAFE FOR YOUR NEWBORN PET. No need to wash your hands after touching it or to prevent your children playing with their pet.
    I have a hub about it . Please leave comment if interested .

    Yes!!! For the animal,because fleas feast on your pets blood. If the animal is very young or old or even sick, It can cause death. In humans ,because some fleas carry diseases. The black plague was started from fleas. Fleas are serious business.
