How do you tell if my pug is in season?

You can tell if your pug is in season by observing signs such as swelling of the vulva, increased urination, and changes in behavior, like increased affection or restlessness. You may also notice a bloody discharge, which is common during this time. Typically, a dog will be in season for about two to three weeks, with the most fertile period occurring around the middle of this cycle. If you're unsure, consulting a veterinarian can provide more specific guidance.
