Hamilton Zoo have recently imported two male African Wild Dogs. They are currently exhibited in the enclosure near the Sumatran Tiger, while the original male and a female occupy the exhibit near the North American Bison. While I don't doubt the elderly male (born 2007), values the companionship of the female (born 2011), I can't help but feel they're making the same mistake as last time, when they imported a 7 year old female as their new breeding female, who was nearing the end of her reproductive years. The elderly male (born 2007) was kept with her until she passed away, instead of being paired with one of the new females (born 2011). By the time this pairing happened, the male was too old to breed. Now, by the time the elderly male passes away, the now middle aged female will be nearing the end of her reproductive years.
