Fleas suck the dogs blood, and causes itch. The flea is a parasite to the dog.
The dog is a Host and the Flea an external parasite.
The relationship between dogs and their fleas is not symbiotic as the dog gains no benefit from it whatsoever. The relationship is purely parasitic.
Dogs/fleas is an example of a Host/parasite relationship.
Parasitism
It is a parasite - host relationship. The fleas as parasites living off of the dog as a host.
parasitism
It is a parasitic relationship. That means that the relationship is beneficial to the flea, but harmful to the dog.
It's not a symbiotic relationship ! It's a parasitical relationship. In a symbiotic relationship - BOTH organisms benefit form each other. In a parasitical relationship - only ONE of the organisms benefits - usually to the detriment of the other. Fleas suck blood from dogs - which can make the dog ill. The dog gets no benefit.
I would say parasitism - host (dog) and parasite (flea).
An army of fleas attacked our dogs,explain it?
Some dogs can. Not all dogs.
Fleas make dogs suffer. They dont help one bit...
Fleas can transmit tapeworms to dogs, but not roundworms, hookworms or whipworms.
