How long is 20 years in puppy years?

Answer 1

140 years old is the correct answer because you times whatever human year by the dog years so 20 X 7 is 140. and a cat year for 1 human year is 16 cat years for one human year...... Hope this helps.... :)

Answer 2

In general, one human year is equivalent to about seven dog years. So, 20 human years would be roughly equivalent to 140 dog years.
