On average dogs can learn approximately 165 words. The more intelligent dogs can acquire a vocabulary awareness of around 250 words. In math skills, dogs are aware of numerical differences up to five digits and can calculate the difference.

It is not a measure of intellect. It is a measure of obedience.
Why I want to take this so seriously is unknown. Perhaps because I'm an advocate for canines.
Dogs can understand our feelings than a 2 year old child.
So I would agree with the "social skills of teenagers" bit.
My dog didn't know what the word "lipstick" meant, but he used to whine every time he saw me put it on, because he knew it meant I was going out.
But are they as smart as cats?
That said, I'm not a huge fan of comparing animal intellect to human intellect. It's like when the study came out saying that chimps had the intelligence of a 2-year old. No, they don't. There are completely different neurological and psychological processes going on in a human than any other animal. That said, I respect the intelligence of other animals and think they are more developed than a lot of people give them credit for. Just not quite like humans.
Could intelligence be genetic? Could it be distributed unevenly in human populations?
What are the implications of this for humans?
First of all, a dog's understanding is highly based on tone of voice and body language. If you glared at your dog and said "good girl!" angrily, she would probably whimper in shame. A two-year-old would look at you as if you were crazy... why would you be calling her good if you sounded angry?
Secondly, there are many things a dog cannot grasp. For example, you cannot ask a dog, "Can you please put away your toys?" Unless you trained the dog to respond specifically to this phrase, it could never understand what you meant, especially if you said it in a slightly different way than what it was used to (e.g. "Put away your toys now.") The human mind is capable of linguistic creativity, something a dog is absolutely NOT capable of. There are a vast number of things that a dog would never understand, for example, getting in someone's way or hurting their feelings.
You're going to have to do much more than that to prove your non-hatred of cats. You will have to post nothing but positive comments at the next cute five cute kitten videos posted here. If you include the words "I can has" or "lolz", your sentence can be reduced to four comments.
However, I think some dogs just have great relationships with their owners despite breed. They can show the same level of intelligence as so called smart dogs. I also think if the owner changes their lifestyle...the dog will either adjust after a while or become bored and destructive.
Oddly enough, my 2 year old child can construct a better sentence than that.
