is it fare to kill the dogs when they become old

If a dog is truly sick and in pain with no chance of getting better or of losing any pain, then killing is merciful. No, they shouldn't be killed just because they're old. And the jungle??? Are we talking about wild animals who know how to hunt and fend for themselves? Or, are we talking about house pets? If we're talking about house pets, it's beyond imagination that leaving them in the jungle is ever considered anything but cruel. House pets can't care for themselves. They don't know how to hunt or protect themselves from predators.

If you had asked me this question one year ago, my answer would have been NO. I didn't think that it is fair to decide about your dog's life. But last year my dog became ill, and the vets didn't give her a chance. Now I can tell you that when you see your beloved dog being ill and suffering so much, you'll think serious about ease her pain. If there is no more joy in her life, and every second brings another sharp pain, if you haven't seen her tail wagging for days, it means the time comes to help her pass away. Yet, I must stress that I agree with euthanasia only for sick dogs, for whom there is no chance to get well. Just being old is not a condition that requires euthanasia. As for your second proposal "leave them in jungle at their own", I have to say it is a cruel decision and I don't agree with it. A dog must die in his family, the place she lived her whole life, not between strangers, or worse, in a jungle!

Its never fair to kill dogs.But what i want to ask you is are these domesticated animals capable of fending for themselves in the jungle in their old age with their instincts diminished?If left alone when young their wolf instinct could enable them to devise ways to survive.If there is a debilitating ailment in old age is it good at that stage in their lives to leave them in the forest to fend for themselves?I think the choice isn't easy.
