When dogs look at a human face, where do they focus ?​

Dogs are wonderful human companions.  They are the first species that humans domesticated and they have a long history of close relationships with people.  

If you spend any time with dogs (I have two wonderful adopted dogs who shower me with affection and fur), then you see first-hand the many ways that dogs can respond to their owners.  A dog may treat a stranger with suspicion, but dances with joy when its owner returns.  Indeed, when one of our grown children returns after a long absence, the dogs respond with excitement.

the answer is: trichonympha lives in the gut of termites and digests cellulose eaten by the termite.

this is an example of a symbiotic association of a protozoan with its mode of association.
