I work in a veterinary practice (as well as in a care home). I often assist in putting animals to sleep. I have had several of mine go that route in the past. More recently, I insist on raising the vein and then releasing it. All I can say is that I know it is the best thing I can ever do for any of my animals no matter how much it hurts me. For each of them (apart from one - who was agressive and that was the hardest decision I ever made in my life - I was releasing them from their suffering) and they each had my individual attention at the end and a very special last cuddle from me. They all went in my arms. I miss them all but know that it is me that is suffering and not them and that is what is important. To anyone in the same position, past, present or future, it really is the best favour you can do for an animal who is suffering. I am not an advocate of euthanasia for humans (that is a different issue) but often do think that we are kinder to our animals than we are to ourselves. Working were I do, for each of them I have the courage to raise and release that vein myself as well as make the decision - that is how sure I am that the decision is the right one. Please can I convey to anyone in a similar position - you may not have the experience or knowledge to do the same yourself. But you can be there for your pet and make that final, most important decision. Yes, it will hurt you, but it will release your pet from his/her suffering. The end will be the same no matter what your decision.
