Many bitches go through a false pregnancy. It is actually a normal physiological function that evolved to help the pups of the pack survive. In the wild, it is only the female dogs occupying the top of the social ladder that actually produce litters. The other bitches only produce milk to help feed the pups. Even with domestication, these false pregnancies can still occur.

Bitches of any age can go through a false pregnancy. Signs are generally seen 4-9 weeks after the end of the dog’s heat cycle. The affected dog may have enlarged mammary glands; when pressed, there may be milk, but some dogs don’t actually secrete milk at all. The bitch may also undergo behavior changes—becoming clingy, possessive of toys, or uneasy. They may also engage in nesting behavior. Some go off-feed, and there may be display of occasional aggressive behavior.

The signs usually disappear within 3-4 weeks however, if the bitch continues to display severe behavior problems, you should contact your Wake Forest, NC veterinarian.
