Jake in golden retriever morph.

"We grafted the essence of the Pemalites into the wolf species. And from that union, dogs were created. To this day, most dogs carry within them the essence of the Pemalites. Not all, but most. Wherever you see a dog playing, chasing a stick, running around barking for the sheer joy of life, you see the remnants of the race of Pemalites. [...] They are our joy, because they remind us of a world without evil. The world we lost. We Chee are all that is left of Pemalite technological genius. The dogs of Earth are all that is left of Pemalite souls."
Erek King[src]

The dog is a domestic Earth animal created by the Chee, who fused the Pemalite essence with wolves.


"I thought about becoming Homer. As I stroked his fur I formed a picture in my mind of me becoming Homer. Homer became weirdly quiet while I did it. Like he was asleep, only his eyes were open."

Jake's first ever acquired morph was his pet golden retriever, Homer, which he first morphed into in The Invasion. Marco acquired an Irish Setter in The Android, a poodle in The Proposal and Champ, a German Shepherd, in The Diversion; Champ was also acquired by Tobias and Rachel, although Tobias was the only one of the three to use the morph.

"Dog is the way to go. No one will even think anything about us being there, since there are always dogs at outdoor stuff. And dog hearing is great."
Jake to Marco[src]

Jake's very first morph was that of Homer, his pet golden retriever. He later used the morph to spy on a Sharing meeting at the beach.[1] Some time later, he and Marco used their dog morphs to sneak into an outdoor concert, where they encountered Erek King and realized he wasn't human.[2] Jake also used the golden retriever morph to track down David's scent when the new Animorph left the Wildlife Rehabilitation Clinic.[3]

After acquiring Euclid, his eventual stepmother's poodle, Marco exclusively used the morph to terrorize William Roger Tennant.[4] Marco, along with Tobias and Rachel, later acquired Champ, the guide dog of Tobias's blind mother Loren, although Tobias was the only one who morphed into Champ, in order to observe his mother.[5]
