Dog anatomy is quite important due to my character being a former Rocket and having access to their labs. An example being their larger visual field of 250 degrees compared to the humans 180 degrees. This makes it so Walter can't exactly slink out of view. Also, dogs digest food slower than humans, which can be useful for Walter in using food as bait in order to escape an undesirable situation. A lower rate of digestion makes it so he can rate how much food he needs to use to cover his escape and make the wild Arcanine as content as possible. Also using the classical pokedex, which states that Arcanine can reach speeds over 200 miles per hour. With that, Walter will discount running away. Of course, if it seems that Walter has too much biological insight and too much knowledge, even for a Rocket member, I will be happy to limit his analytical side to just his pokedex.
