Answer
Decidnig to put your pet down is one of the hardest things in the world to do!  I agree that when you think it is right.  When she is in alot of pain all the time and she will let you know she can't go on, but also if the medication is costing you alot, that is something else to consider if you know she isn't going to be around much longer.  Some people can't can't put thier dogs to sleep because it is to hard for them, you have to decide for yourself.  I will keep Snooker in my prayers.  Good Luck
