13 year old lab quality of life question
My yellow lab is 13 years old and the last few months he had deteriorated a lot. He has a bad right rear leg . He has a hard time getting up from seated. He also in the last few months become incontonent. He is over 100 lbs and when he urinated it is a huge amount. Thank god for the make shift diapers I concocted but they don't always work. He is going deaf and pretty sure blind as well. He now had thyroid issue and has recently contact ringworm whiny is all over his coat and looks terrible. I am so conflicted and don't know what to do. I don't know if he is suffering , if he wants is in pain ( he is in pain meds twice a day). I haven't had to deal with this before. My two animals that I had to put down got sick and it was clear the right decision. With my lab I feel he had more time but when is the right time to let them vow out with dignity. If anyone has had this situation or similar I would appreciate your advise.
thanks to all,
