Why "I see the dogs" is wrong?
I see dogs sounds like something I would use to answer an inkblot test.
It is not wrong. I reported that this answer should be accepted.
Whether you would translate as “I see dogs”, or “I see the dogs” would depend on context, of which there is none in this exercise.
I will add it because it is very similar to https://forum.duolingo.com/comment/27879221
