Matilda, a small Chihuahua, developed a strange behavior at 15 months old. She started carrying around a toy that resembled a baby in her mouth, whining and pacing. This behavior was a sign of false pregnancy, possibly triggered by hormonal changes. Signs included enlarged mammary glands and sometimes refusal to eat. Spaying can prevent false pregnancy and other health issues in female dogs. Male dogs can also exhibit similar protective behaviors over toys, although not due to hormonal fluctuations. Dogs may carry toys while crying for various reasons, such as anxiety or resource guarding. Through training and playtime, owners can help alleviate these behaviors.
