I had one who vocalised in the ring. He was eventually dual champion, GB/IR, but he taught himself to recognise those red rosettes indicating a class win. And you could almost pick out the syllables 'Yes, I was clever. Yes, I got a red !'
It wasn't a crow or a yodel, it was positively syllabic - conversational almost.
The Basenji in the video is vocalising exactly like all my boys have done over the years - mostly at 2 in the morning when they wanted sex.
As soon as the girls showed any signs of seasons, the boys were banished to a des-res (desirable residence) up in the orchard with access to walks in a completely different direct to that followed by the girls who remained in the house.
I put a nursery alarm into the large garden shed we used as a kennel on these occasions so as to share the pain of the rest of the village. . .
It was a relief when the girls dried up and the three boys came back into the house. Not only for me but for all the neighbours !
