Diagnosis and Treatment of Canine Pseudopregnancy

Pseudopregnancy occurs when a female dog displays physical and/or behavioral signs suggestive of pregnancy, despite not being pregnant. While pseudopregnancy occurs most frequently in intact females 6 to 8 weeks after estrus, spayed females may develop the condition particularly if spayed during diestrus.

No specific test is available to diagnose pseudopregnancy, and research literature on the topic is scarce; therefore, diagnosis usually occurs by identifying characteristic signs and excluding other conditions, such as pregnancy and pyometra. With this in mind, researchers recently conducted a questionnaire-based study to further understand the prevalence, diagnosis, and treatment of pseudopregnancy by general practitioners in the United Kingdom.
