Is it unusual for a westie to go into heat 3 times a year?

It is not uncommon for a West Highland White Terrier (Westie) to go into heat twice a year, but experiencing heat three times a year can occur, especially in younger dogs or those with irregular cycles. Factors such as age, health, and individual hormonal balance can influence the frequency of heat cycles. If a Westie is going into heat more frequently than expected, it's advisable to consult a veterinarian to rule out any underlying health issues.
