Fleas from a dog can jump onto any part of a person that is close enough for the flea to make the jump, so yes they could jump onto your head where they will find a home in your hair. You will then have a flea infestation in your hair. It is very easy for this to happen. If this happens there are special powders or shampoos to git rid of the fleas.
No they jump off and reproduce
yes, a house dog could get fleas...of course you go outside and walk around, your shoes touch the ground and your clothing picks up many things. When you get home, fleas can be on what your wearing and transferr to your dog. Also when you like your dog outside, you dog can catch fleas as well.
Fleas on a cat are probably either dog fleas or cat fleas (these are two different species, but despite the name, either can survive on either a dog or cat ... or for that matter on other mammals). Both of them can and will bite humans.
the fleas would jump from people to people spreading the infection.
Yes. They jump off and into the carpet, etc. furniture. One way to eliminate fleas on the dog is to bathe them, neck down, then do the head. You may see the fleas going down onto the nose or into the ears. I use Eucalyptus soap, but as long as you use soap and water it will drown the fleas. Vacuum a lot, and dispose of the bag immediately to the trash. Soap works faster and more safely than pesticides with fleas. Be sure to lather up the dog or cat and don't hurry to rinse off... let the fleas absorb into the lather, then rinse. Shampooing will eliminate the live fleas, pesticide will not; it weakens them (and your dog).
No, cat fleas and dog fleas are two different species.Cat fleas can also affect dogs, but dog fleas do not affect cats.Cat Flea: Ctenocephalides FelisDog Flea: Ctenocephalides canis
A dog fleas habitat is the dog itself.
yes, if your dog has fleas
They can either attract from other animals that have them or roll on something that does. There is even a chance that fleas will jump onto your dog.
Fleas can jump up to 150 times their own body length, which is about 13 inches.
Fleas jump to move from one host to another, they do not fly.
No, not at all. All it takes is for your dog to walk, sit, lie, or brush against a tick and the tick seizes the opportunity. With fleas, it's even easier because they can jump a long distance to reach your dog. And since fleas detect the dog's body heat from relatively long distances, so just a couple of minutes outside is all it takes.
