You speake from your own experience matey and I respect that but I have seen the very thing Hedz talks about many times and it happens........all these dogs were raised differently, some lived out, some lived in just as any pet would.......they were not overmatched or given too much, too young.......it was all steady away with good decent owners, they were from good stuff but didnt make it.
Plenty of lads will tell you a similar story.
A dog can have a heart as big as a bus, but if its lacks size or sense to back it up then its gonna get hurt and there is only so much any animal can take.
