Was wondering

How can you tell? Are you a dog? If so can i pet you?

You both have good points. We can't ever truly know what anything else perceives, even other humans. But 1:7 is a general guildline of overall mortality used to relate lifespans. It's also a poor one. In actuality the ratio changes based on a dogs age and breed. Age wise most dogs undergo pueberty and sexual maturity by 12-14 months. While some humans experience puberty this young it is rare (and classically rarer.) small breeds tend to live years longer than large breeds as well, making breed relative age a factor. While we can't say they don't- it's logically faulty to assume a dogs perception is based off a number we chose to reflect a good average in comparison to human life times. We know that dogs seem to process time different as well and posses a different intelligence that isn't easily compared to a human of a given age either. There's also theories smaller creatures see time slowed sped up compared to larger creatures. So it's debatable but unlikely 1hr=7 to dogs.

Yeah. Dogs have no concept of time. It's "My bladder is full" or "They'll be back in a minute."
