So I see someone hoarding star dogs from this month on the swap thread. I send them a suggestion, since I see no growing pets for trade. They send it back with two pets of mine, both which could be valuable. I was surprisingly happy at the moment so I change it to a hoard swap. They then ask for 2 dogs. Yes, I know many are looking for that horse. But I have 2, and even if it does become uncommon, it's unknown right now. Don't ask for overpay.
At least they accepted a fair trade in the end.
