Pseudopregnancy is a hormonal condition in unspayed female dogs where they exhibit physical and behavioral signs of pregnancy (nesting, milk production) despite not being pregnant. It occurs 6-8 weeks after a heat cycle due to dropping progesterone/rising prolactin.
Monitor the animal closely. If Key/Common symptoms worsen, seek help.
Report for RecordThis is a hormonal event, not a disease. Not contagious.
Signs begin with mammary enlargement and nesting behavior. Milk production may follow. Aggression or guarding of toys ("surrogate puppies") is common. It resolves spontaneously in 2-3 weeks.
History of recent heat cycle is key. Ultrasound or X-ray confirms the absence of fetuses.
Mild cases require no treatment—do not stimulate mammary glands. Severe cases with behavioral issues may be treated with hormonal suppressants (Cabergoline). Spaying cures it permanently.
Spaying (Ovariohysterectomy) is the only prevention.
Excellent. It is a normal physiological variant, but recurrence is likely after subsequent heat cycles.
