I believe some tracking dogs and hounds have the keenest sense of smell.
No, not as a rule. Dogs rely on the sense of smell and do not hunt by sight primarily, as do cats.
Yes wild cats are more common.

To me, I think that dogs have a better sense of smell. That's why policemen use dogs to track criminals.
According to scientists, they did. In fact, they were thought to have an even better sense of smell than dogs, and dogs' sense of smell if around 60 times better than a person's.
Cats have better hearing than dogs as cats can rotate their ears 180 degrees.
A domestic cat can smell with roughly 200 million smell-sensitive receptors (humans have 5 million). A domestic dog can range from as low, in comparison, as 125 million to as high as 220 million depending on the breed. Scenthounds receptors are obviously on the higher end of the scale. On an average the cat can smell better than the dog but the specific winner goes to the Dog breed of Bloodhound, which can have as many as 300 million. This makes them a clear winner in breed but not in genus.
I can't say. All dogs have a very good sense of smell, big or small. Springer Spaniels (Small to medium sized dogs) and Bloodhounds (Large dogs) both have a good sense of smell.
Dogs have the best noses, followed by cats. Humans occupy a distant 3rd place in the "by a nose" category.
There sense of smell is definitely better than ours
yes it is true dogs smell much better than humans
