How long does a cavachons first heat last?

A Cavachon, like other small Dog Breeds, typically experiences its first heat cycle between six to twelve months of age. The heat cycle usually lasts about 2 to 3 weeks, during which the dog may exhibit behaviors such as increased urination, restlessness, and swelling of the vulva. It's important to monitor your dog during this time and consult a veterinarian for guidance on care and potential breeding considerations.
