When Rebecca finally found her long-lost Schnauzer, Casey, the dog beamed with happiness. Can a dog faint from the overwhelming emotion of seeing its owner again? While it may seem improbable,
dogs are capable of experiencing a wide spectrum of emotions, with some study showing that complex sentiments such as love and
shame may be within their emotional range. Dogs may experience an adrenaline rush at times of tremendous joy or excitement.
Adrenaline causes a reduction in blood pressure, which might lead to fainting if taken in large enough levels.
However, until such occurrences become chronic, one need not worry. If a dog does faint due to delight, providing them some time to recuperate and showering them with love and food will help.
