Looking at stats today for something else, I noticed the continual decline in registrations of purebred dogs.
The ANKC stats show that in 1986 - 95,792 dogs were registered. In 2008, this figure has declined to 63,387.
Given that the population of Australia has increased by approximately around 5,000,000 in that same time period, this decline would appear to be a concern.
I should point out though that there has been a recovery somewhat in the last 2 years. This has occurred before however before the figures returned to the downward trend.
