Both of our bitches didn't come into their first season till they were around 14 months.
Speaking of seasons...we have been having fun and games here with Bree in season. This causes a lot of bedroom shuffling, whimpering and howling. Lockie has gone off his food and is being the biggest sap. What has worked well is putting Bree into a large soft crate at night so we can all be together. Lockie settles down quickly and we have a peaceful night without howling and continual whimpering. Now if we could just get the cat to shut up we could get a full nights rest
