Thanks very much everyone for the welcome. I really appreciate it.
I always happy to talk dogs and pigs too. Always keen to learn new things or try new techniques. I'm a great believer in a few tried and true things as well but like to keep up to date in case it will help me get more boars...
On Donna, she's RIP now but she was one of our family of dogs. The go back to dane, EBT, wolfhound and Eng mastiff. They've been bred as a family for some time and the emphasis at our place is on proven ability rather than looks. So some are bigger, some smaller, some hairy and some not so hairy but they will all find pigs and stop them. So that's Donna.
Anyway, thanks again for the replies. Here's another decent boar I got with Bob the dog. Bob got him on his own despite the steepness of the terrain ( you can seen in the background). The pig dressed 73kgs (160lbs) and that's what I then had to carry back up that hill. Got him last year on my 49th birthday so I was very glad the boar didn't make it any further down the hill.

Cheers.
