"Are you sure you want to do this?" asked Thomas-as-Sarah.
The original Sarah nodded. "It's fun being a dog. No responsibilities, no homework. I don't even have to clean up after myself," she added with a smirk.
"You know what kind of risk you're taking, right?" asked Ian-as-Thomas. "We all have read about the history of this amulet. It has a habit of doing people in at the worst possible moment. We've all been playing a bit of Russian Roulette even with what we've been doing. What happens if the amulet gets lost or stolen? What happens if we simply decide to leave you that way?"
Sarah seemed thoughtful, then smiled, "I'm willing to take the risk. Besides, I'm talking about being in this form for at least one litter, maybe a couple. By then I might not want to be anything else."
They bounced the idea back and forth, and finally settled on a long term plan. For now, Ian was going to stay Thomas and Thomas was going to stay as Sarah. Sarah would be Honey. They used the amulet to make the changes, then hid it behind a baseboard that was itself behind a heavy shelf. If you didn't know where it was, you'd have to rip the house to the studs to find it.
The arrangement worked pretty well for a few weeks, and Honey threw herself into her role as the family dog. When her heat inevitably came a few weeks later, she discovered that her roommates had planned ahead.
