Breeding Hunting Dogs in captivity still seems rather a hit or miss affair. Port Lympne have had success in recent years, while others have none. Maybe its due to complex dynamics between the individuals within a pair or larger group. In the wild I believe only one female(the dominant one) breeds in a pack at any time. Port Lympne tend to keep the adults in pairs, rather than larger groups, so there are no 'subordinate' females in these pairs and each pair can potentially be a breeding one..
Some years ago Port Lympne sent 2.1 dogs to Cricket St Thomas, which still has them. These have never bred, perhaps because they are siblings and have always lived together? I think if they changed one of the sexes for a new individual or two, things might be different, but its probably too much effort....
Another fascinating subject, my friends.
Group dynamics in hunting dog packs are just the one aspect to this equation. If packs get to be too large they eventually break up into new alliances with former subordinates becoming dominant in new settings (the infamous 1+1+1+1 = 2 packs). F.i. if a pack has say 15-20 members and when they meet up with another pack of say 8-12 members surely altercations will occur.
But it is exactly at that moment that opportunities for genetic exchange do and will happen. With territorial boundaries re-instated during altercations subordinate males or females from pack X seize the opportunity and produce new alliances with subordinate females or males from pack Y. The net end result may be the original packs X and Y plus 1 or even 2 further packs all made up of related males/females and unrelated females/males. The hunting dogs will simply seek each other out and determine whether they are compatible mates there and then.
The very basics of hunting dog group structure is that by definition all male pack members are related to oneanother, same goes for the female composition of the pack (viz the above).
Another important aspect is that there is just one dominant pair that will breed and sire offspring in any given pack. All its individual members are involved in the rearing of any new pups. If another subordinate female in the pack is mated successfully - which occasionally does happen in the wild - the dominant female will kill the subordinate's new pups and/or prevent the other pack members from assisting in their rearing. The relevance of this is that all resources are geared towards rearing just the one set of pups, thereby increasing the chances of rearing success.
Even in captive environments - whether you set up just a pair or a group setting - all these factors come into play.
A) Setting up a pair means really challenging the nature of hunting dog troupes and these only work when the pair is compatible in the first place. If not compatible they will not breed.
B) Setting up a group formation with 2.1 related individuals will not succeed as their very - and even perceived by all group members - relationship as brothers with sister prevent them from breeding. It is a natural mechanism to prevent inbreeding depression and a major aspect in maintaining fitness in hunting dog packs.
C) Group formation with unrelated individuals on either side of the sex divide will only succeed if the proposed group formation members work out to be compatible with oneanother.
Thus the challenge to form compatible breeding groups in captivity is borne and ... no it is not a simple one. As you all know: in captivity we decide what individuals are paired up and if the chemistry just is not there (the compatibility complex) a working hunting dog troupe is out the window. It is therefore a matter of try, re-try and re-try.
