False pregnancy, or pseudo pregnancy, is a term used to denote a common
condition in a non-pregnant female dog that is showing symptoms of pregnancy,
lactation, or nursing, without producing puppies.
The affected female dog shows these symptoms about a month or two after her
estrus (heat) is over. A hormonal imbalance is thought
to play a central role in affected female dogs. Depending on the severity of
problem, the symptoms may last for more than a month.
Let's hope for the best for next time!
