Bless his heart, hs just looks so lethargic and those spots do look quite severe. I agree with TxVicki. If he has something that is reasonably easy to treat that will improve his quality of life, then that would be great. I agree with you, too, about not letting him suffer. I think we are here as caretakers of these precious animals and part of that is making sure they have a good quality of life and don't suffer unnecessarily. That is a very difficult decision and I feel that if you haven't explored a few options that could improve Toto's health before making that decision, that you might later second-guess yourself. I pray for you to have the strength and peace at heart to make the best decision for Toto and the strength to deal with your Mother and any push-back she gives you. I also pray for Toto's comfort and healing. Please keep us updated on how he is doing. My heart is breaking for you to have to see this fella that has been part of your life for so long declining as he is.
