I think there needs to be a Icon for when a dog is pregnant.

A little Stork, or Rattle, Bassinet, or Carriage, perhaps?

Also would be very helpful if it would Remove the In Heat visuals.

I have a hard time remembering exactly which or how many females are pregnant - and then I end up expecting 5 litters at once - oops! I also like to check between my females to make sure I'm not using the same stud 5 times.

hope this sounds good and helps many, thanks!
