It's so much easier with a dog, we have different rules and attitudes. I have no problem taking a dog that's in it's final months to the vets for the final time and not wasting money on veterinary care that won't justify the cost. I've known from day one it will come to that.
But it's just not so simple with people that have the power of reason, whether it be the sufferer, or the family. I don't know the answer.
