I feel your pain Ive had 2 of my dogs pass away within a year of each other here recently. both of them had cancer and we had to put them down and they too were rescues one we got when I was in 4th grade after my step dad found him abandoned in a substation, the other was from a rescue place. They had good lives and are in a better place now and no longer in any pain. Time helps with all things Chance The first to go with cancer was the rescue R.I.P. 4/25/11 Max Found in a substation R.I.P. 3/27/12
