Some classic examples of ritualised aggression interactions in the main pack, mostly between Kanti and Bicho. In these high arousal moments you will hear a lot of growling and snarling from Kanti paired with posturing and muzzle grabs (sometimes hard, if Kanti is over threshold) as well as pinning, mounting and agonistic puckers. Bicho will display exaggerated pawing, licking and whining. A lot of the times Bicho is the one who initiates this and often will elicit these responses from Kanti.
Why he does this is unclear. There has been many times where Bicho has pawed Kanti in the face and caught his nail on his mouth, which makes Kanti retaliate.
Behaviorally, these two are very interesting to watch.
