shes female, nearly max weight, a DH and has decent vitals. not only that, but shes had a DH pup in both of her previous litters

if you plan on auctioning her off while shes still pregnant, id say have a starting bid of around 100 mushrooms, minimum increase of 50 mushrooms and autobuy of maybe 3-5 apples.

you'll likely get more out of her if you max out her battle, too!
