How to know when it is time to let go of dying pet

One of, if not the hardest decision you will ever have to make is when it is time to let go of your sick pet. Everyone wishes they would just go to sleep and not wake up when it gets to the point where you know they are not going to get better and they keep getting worse. How to know when it is time? Some say you will just know, others have systems like http://www.petmd.com/blogs/fullyvette... which is always good references but in actuality most of the time the owner knows it is time however just does not want to let go. The decision may seem to make you feel guilty however it is one of the most unselfish things you can ever do and not to make the decision and just keep hanging on can cause unnecessary suffering and that is the selfish thing to do. Hopefully this short video can help you make the tough decision. We almost did it 2 full weeks before we had to and thought it was time however after the 2 weeks, then we knew it was time. Very difficult to do but the best thing to do when you know they are not getting better and stop eating, losing weight, etc. Good luck with your decision.
