No. the dog ages faster after reaching adulthood.
It's like 2 - 2.5 man years thereafter, but that is
just an estimate.
Here's the BEST WE CAN DO!
91 dog years is ABOUT
91 = 2X + 7
84 = 2X
X= 42
So it is ABOUT 42 man years.
Zinc is the LEAST we know about so Zinc = X
Neo = x-14
Rhanza = X + 6
X + X-14 + X + 6 = 42
3x - 8 = 42
3x = 50
x = 50/3 = 16 and 2/3
Zinc is 16 and 2/3
Neo is 2 and 2/3
Rhanza is 22 and 2/3
91 = 2X + 7
84 = 2X
X= 42
So it is ABOUT 42 man years.
