I havent seen the programme,
but in response to your first statement, i dont think it is the type of dog at all that depends on how 'brilliant' it is!
We were very niave unfortunately when we got our 2 dogs & kind of assumed good behaviour comes with pedigree, we learnt the hard way that is not true at all!
My sister got her staffie cross for �20 the same time I spent �500 on my pedigree Samoyed, and her dog is amazing! He is so well behaved and a perfect little fella!!
