The question is then how to evaluate your pet’s quality of life objectively? The categories that need to be evaluated include mobility, pain, hygiene, eating/drinking, general happiness, and good days versus bad days. The best scale I have found for this purpose is the “HHHHHMM” Quality of Life scale developed by Dr. Alice Villalobos. You can find this scale and how to use it at http://www.pawspice.com/index.php?option=com_content&view=article&id=5&Itemid=10
I had a 3 year span where 3 of my dogs got to the point of making this tough decision. This was the scale I used, and was grateful to be able to reference it. Since they don’t have a deciding voice in when “it’s time”, please make the priority an evaluation of their quality of life and rest with a good conscience when you do because you’ve objectively evaluated it. Your pet is counting on you!
