Bentley

Bentley is a young English Bulldog in Bitch's custody.

Personality
Of all Rachel's dogs, Bently has the most open affection for Taylor.

Abilities and Equipment
Has the abilities of any enhanced dog of Rachel's. On his first outing Rachel fitted him with a muzzle so she could have better control of him.

Background
Presumably much like that of other dogs Bitch rescued.

Post-Leviathan
After bringing him along to capture Shadow Stalker, Bentley appeared before? his master used him during a raid on Protectorate ENE Headquarters. He followed a command by someone other than his master, when Skitter ordered him to attack Kid Win and praises him, resulting in immediate retaliation from Bentley's master.

Post-Slaughterhouse Nine
Helped with cleaning up the Boardwalk.

Post-Echidna
Deployed to and survived New Delhi.

Post-Timeskip
He was not seen among Rachel's dogs when the end of the world approached. Given the environment he was living in he may well have died.

Trivia

 * It should be noted that as an English Bulldog Bentley does not have the typical american bulldog issues of being to low to the ground or having long drooping jowls.
