Online vet, Dr. Marie

Dr. Marie replied:

Any dog can have their first heat cycle any time after 6 months of age. For small breed dogs, generally the first heat comes around 8-12 months, but sometimes it can be even later than that.

Ideally, it is best to have a dog spayed before they go through their first heat cycle. This will greatly reduce the risk of getting breast cancer later on in life.
