${\bf \red {\huge{answer : }}}$

The dogs weight increased from 64 pounds to 80 pounds.

80 - 64 = 16

so , the dog's weight increased more 16 pounds.

$\pink {\sf{hence , (16)/(80) * 100 }}$

$\red{= \frac{16}{8 \cancel{0}} * 10 \cancel{0 } }$

$\purple{= \frac{ \cancel{16}}{ \cancel{8 }} * 10 }$

$\blue{= ( 2)/( 1) * 10 }$

$\green{2 * 10 = 20\%}$

Therefore , the dog's weight increased by 20%
