If your female dog doesn't produce milk, mother items or show nesting behaviours, it seems logical to conclude that she doesn't suffer with phantom pregnancies. Nevertheless, there are two types of phantom pregnancies.
Overt- . An overt phantom pregnancy may include physical symptoms, such as swollen abdomen, weight gain and swollen mammary glands that may or may not produce milk. Behavioural symptoms can include excessive licking of ni***es, mothering items, nesting and resource guarding.
Covert- If your dog experiences a covert phantom pregnancy, they will not show any physical symptoms or the typical mothering behaviours, however, sudden behavioural changes may be observed, such as resource guarding, anxiety, reactivity and even aggression.
It's important to be vigilant for these behavioural changes during this stage of their cycle (no matter how subtle) and carefully manage their environment until the phantom passes. This may mean breaks from walks, increased enrichment in the home, separation from or avoidance of young children (especially in cases of aggression or resource guarding) and keeping their life quiet and as stress-free as possible.
Spaying when the prolactin levels are too high, can cause a persistent phantom pregnancy. This can cause behavioural symptoms, such as aggression and reactivity, to persist if there is no medical intervention. Therefore, it is crucial to only spay during the anestrus stage of the cycle, 4 months after their last day of oestrus to allow the prolactin levels to drop and significantly reduce the chances of a persistent phantom pregnancy.
