I agree with what I quoted though I would say its seriously not enough.Jean Hag said:Animal cruelty should be a felony, and a serious one on top.
Stop having your heads up your asses.
What I suspect happened here is the issue developed, they tried to keep up with the food intake but realized they couldnt likely because they simply could not afford to. (Seriously, St Bernards eat like horses, now imagine one thats insatiable)
So I guess they decided instead of taking it to a vet (which they likely could not afford either) Or putting the animal down (Understandable given how hard guns are to come by in the UK and could you image trying to kill a dog the size of a human without a gun?) they decided to let nature run its course.
On a very insignificant level I can empathize with the difficulties the circumstances present. Its not what I would consider abuse. Its neglect and that is a completely different thing.
What they should have done is surrendered the animal, allow it to get the treatment it needed. It sucks to loose a pet, but they lost it anyway, and got a completely inadequate punishment for it.
