What happened is that when Mark and June and Dustin had been transform what had happened is that the magic seemed to know that Ty still wanted to punish them more because where Mark had been exchanged with one of the bitches same as Dustin and June with Buddy.
It also had made it so that all three had made it so that all three won't attack ty or anyone else in the house. Ty realized that with buddy and the other only have very little human knowledge. So he had transferred the knowledge with Mark, June, and Dustin but not there personality .
It was when the three original dogs were now able to talk that the dog that had been Buddy in now June's body told Ty thank you for the knowledge but why me am female. Ty then realized that when June and Mark had been transformed had been changed into the opposite sex. Ty then also realized that the new Mark and June are naked and then wished that they would head to there bedroom and become horny.
Ty then calls the dogs that were the 3 original humans and they all come and he sees that the collars all have tags and dog licenses and he sees that the tags have new names.
Mark's now have the name Marcie, June's says Justin, and Dustin's says Daisy. Ty had then changed it so that Mark, June, & Dustin will age slower then normal dogs but then also had changed Dustin's dog age to that of a human kid age of 5 or 6.
Ty had then made it so that everyone had remembered that now Mark and June had a daughter named Debbie.
