No
No, flea treatments are only designed to kill the infestation of outside parasites. In order to kill worms, a dewormer has to be administered.
The tapeworm Dipylidium caninum can be transmitted when a flea is swallowed by pets or humans.
The teeny tiny black worms on your couch are likely flea larvae. Flea larvae are the offspring of adult fleas and they feed on organic debris such as skin flakes and pet dander. It's important to address the flea infestation by treating your dog and home with appropriate flea control methods.
Most fleas carry Tapeworm so you can get the worms.
No, unless the dog chews on it or swallow pieces of it.
This is the Alder Flea Beetle. You can see this on the wensite below -
Of course not.
There is no symbiosis between a flea and a dog. The flea is a blood eating parasite on the dog. There is benefit to the flea but not to the dog so there is no symbiosis.
Yes....By swallowing a flea infected with a tapeworm larvae. This process begins when tapeworm eggs are swallowed by flea larvae (an immature stage of the flea). Contact between flea larvae and tapeworm eggs is thought to occur most frequently in contaminated bedding or carpet. Next, the pet chews or licks its skin as a flea bites; the flea is then swallowed. As the flea is digested within the pet's intestine, the tapeworm hatches and anchors itself to the intestinal lining.
No "normal" per se, but not uncommon. This is caused by the cat injesting flea eggs. Need to put the cat on Frontline or another anti flea medicine
