"Slow apartment sized elevators (which this looks like) go about 1mph. Let's say it takes an average of 10 months for a dog to go from puppy to a fully grown adult.
10 months = 305 days = 7320 hours.
Short elevator ride = 7320miles (close to the diameter of the earth)
Assuming dog is 16 years old in second photo:
16 years = 192 months = 5856 days = 140,544hours."
