I am sure it is instinct Des, for although Gwen does not know how to play ball or play with toys, she constantly works on our walks, and has recently taken to the water and brought me on two occasions from the reeds a young Coot then a Duckling... placed in my hand then sat in front of me... both birds were unmarked and unharmed, I gave her a treat then slipped them back into the water where they both happily paddled away back to Mum.
She does not know how to play... but she knows how to work ?... good on the whistle too.
Well done to young Bonnie though... she would take to training really well.... I think Gwen is perhaps too old at 5 years, though she may have had some training earlier in her life ?
