Boomer is a dog. He has brown eyes and brindle coloured fur. He is the mascot of Rae-Rae's Pumpkin Farm in John Seed's region, Holland Valley in Hope County in Montana, United States. Boomer is insanely loyal, trusting and loving, but he will not hesitate whatsoever to kill the members of the terrorist cult, the Project at Eden's Gate led by the radical preacher Joseph Seed and his 3 siblings as they murdered his owners, or help the Junior Deputy, a human, take down the cult.
