In order to get the dachshund goal, you have to have one laberdoodle which is, I assume, a Lab/poodle crossbreed. This is the next to the last item needed to get the dachshund.
If I spend the 21 gems on the lab, am I going to have to spend more gems to complete the final item of the goal? And if so, how many more?
And once I have the dachshund, does it cost coins or gems to get the dachshund's mate and offspring?
