What if your scotty appears to be heat and she is only 9 months old?
Reproductive maturity can be reached before dogs have finished growing.
Female rabbits are seldom out of heat in warm months. In the winter it is harder to catch them when they are in heat. It is a natural survival instinct carried over from wild ancestor's. Wild bunnies only breed in the months when they are sure they can raise babies before the food gets scarce. Domestic females are only out of heat 2 or 3 days a month.
Should you be worried if after six months of the last heat your dog still has not come to heat again?
No, as not all Dog's come into heat every six months exactly. Some may have a heat cycle eight or nine months after the last one. Smaller breeds usually have their heats slightly further apart than larger breeds. Also, some breeds of Dog, such as the Basenji, only have one heat cycle a year so it is nothing to worry about.
