Most female dogs normally have eight or ten nipples. However, for those that have never whelped puppies, some of the pairs can be hard to find under their fur.
Cats usually have eight nipples but sometimes there can be extra ones

Boy gerbils actually do have nipples but less visible then female and seem to be less in count having a possible four.
It depends on the species. Most possums of Australia, such as the Ringtail possum, the various Pygmy possums and the six species of gliders, have four nipples. The Brushtail possum has just two nipples in the pouch. The opossum, which is NOT related to possums, has thirteen nipples arranged in a circular form. There may be as many as 17 nipples.

female look them after and male defend them
Female dogs are in heat for up to four weeks. However, there is a small period of time that they are fertile and therefore will only be receptive to contraception for a few days. Pregnant female dogs carry their babies for 63 days.
