My 3 year old bitch was due in season in August and still there is no sign of it. Her seasons started when she had just turned a year old. She had a season last August and then again in February but so far nothing. Should I be worried?

Nope it is not unusual for bitches to be late or early, usually just so they can inconvenience us ;)  I am waiting on my youngest as she is overdue.

My Jozi in 2006 was over 2 months late and her daughter was early, both were supposed to be mated with one litter reared before other born they ended up in season and had their pups within days of each other, never again.
