why don't dogs acknowledge/recognize themselves in the mirror?

What you're talking about is "the mirror test." It takes a certain amount of intelligence to look in a mirror and recognize that it is a reflection rather than just another space. Those animals are also able to recognize a reflection as themselves. Only a few animals pass the mirror test. Humans, chimpanzees, gorillas, orangutans, elephants, dolphins, and possibly pigs pass the mirror test. Some intelligent birds also have passed the mirror test--I believe crows and blue jays.
