That is not a mastiff my friend in england has two these are mastiff's.

I think it says on the report about it that it was an Argentine mastiff? who knows?

This Ido NOT understand. We have 2 dogs, both boxers, one 9 months old, one 5 months old.

yes on occasion as a result of exuberance they have on occasion "slipped us the tongue" but it is NOT encouraged and usually results in excessive mouthwash usage post occurrence,,

but we have lovely dogs.... they are not the best trained in the world, but have the basics of "doggy good manners". They will walk to heel, they come when called (Sit and stay is another matter - usually they are too excited! they will sit, but stay????? depends on circumstances). we try to stop them jumping up - caesar (the older one) is getting it, Hector (the pup) still can't comprehend... he is still at the whine-and-taunt-the-cats stage! and everything is just SOOOOOOOOOOOO exciting!

It looks like this was a warning bite as she was invading the dogs personal space while it was tightly held by the owner (I guess the dog did not know it was Valentine's day). There is no way of telling if a dog is aggressive or unreliable based on a 1 minute video like this.

that didn't look aggressive to me, it was a 'get out of my face nip' if it was aggressive it would have latched on. older dogs do it to puppies all the time...my father in law's jack russell put my bulldog on its back as a warning once.

That presenter is beyond stupid! Getting in the face of a restrained dog is bound to result in it getting uptight. The signs were there long before it 'nipped' her!!

So take out the presenter and put in a two year old....

Still the toddlers fault when half their face is missing from a "nip"?

I've had a dog in the family for 30 years (not the same one obviously), and at any point the dog shows that sort of aggression towards a human, it's days are numbered.

As much as I love dogs, they must always come second to humans, no argument.

Might sound heartless, but these are creatures we imprison with us, only allowing them out when WE decided it's convenient and feed them when WE decide it's dinner time.

I wouldn't be letting a two year old get in the face of an dog I didn't know the background of.

but generally, yes I agree with you.
