Growlithe appeared alongside Morrison's other Pokémon as they are being introduced to Ash and his friends. Morrison used it in a Double Battle along with his Gligar against Gavin and his Marowak and Machamp in the Ever Grande Conference. Growlithe went to use Take Down, to which Marowak retaliated with Headbutt. As Gligar went to help Growlithe, Machamp went to use Cross Chop. Growlithe then fired a Flamethrower, which Marowak deflected by spinning its bone club. Machamp then used Dynamic Punch to inflict heavy damage to Gligar, followed with a Cross Chop, to which Gligar knocked Machamp down with Steel Wing.
Marowak, however, fired Bone Club at Growlithe, who fired Flamethrower. Marowak endured the attack as it charged with Headbutt, then used Ice Beam to strike Growlite's leg. With Growlithe immobilized, Marowak used a Bone Club to hit it. Gligar fought with Machamp, and exchanged blows. Marowak threw a Bonemerang, to which Growlithe used Flamethrower to hit both Marowak and Machamp. Gligar attacked Machamp with Steel Wing, avoiding its Dynamic Punch, and defeated it with Guillotine. Marowak used its Bone Club, evading Growlithe's Flamethrower and defeating it. After a day of hard training with Ash, Morrison laid on grass with his Pokémon, including Growlithe, to rest a bit.
After his Girafarig was defeated, Morrison sent Growlithe to battle Ash's Corphish. Growlithe evaded the latter's BubbleBeam, then used Agility. However, Corphish pushed Growlithe away and defeated it with Crabhammer. Morrison blamed himself for having Growlithe defeated, to which Growlithe licked his face.
