As much as possible, maybe IRL with the right person

Want a hypnotist to brainwash me into a dog

Straight sub looking for canine brainwashing and dog training

PM for e-mail

Former human looking to be bound, brainwashed, and broken into a permanent dog. Collared, craving dog food and slurping water from a bowl, tongue stretched, listening to hypnosis files on repeat until he is nothing more than a rutting stud in heat.
