I have read a dozen reports of this, and I agree, it doesn't add up at the moment. The latest update says there will be more information at the end of the week, when the post mortem will take place. However I read that the parents have been released but were originally detained on manslaughter charges. This is standard procedure though I think. It sounds like the dog must be a husky/mal cross, because there was a mention of blue eyes somewhere and its extremely rare to get a Mal with blue eyes.
The part that worried me was that the chap bought the dog in a pub 'because the people didn't want it'. Does that suggest it was a problem dog ? - yet neighbours say it was quite docile.
Still, a terrible tragedy. Also, as mentioned, our breed is going to come under scrutiny again.
