I'm sorry for your loss man. I'm slowly saying goodbye to my big guy (Moose the Mastiff). He's got major arthritis in his rear. He's on a decent NSAID now and he on apain med in the afternoon noon. Doing better, but winters right around th corner. Moose was a rescue from great lakes mastiff rescue. He was kept entirely outside. His original owner gave him up. Dropped him off at a vet mid January in Michigan. Sometime before the vet opened. He was tied to a tree outside and his owner zip tied a note card to his collar that said "Please put him down. No use for him anymore. The vet found out he had an ACL tear, a fractured tail, and a healed skull and jaw fracture. They fixed him up. He spent a lot of time with a foster family. That's when I met Moose. He came home with me after the paperwork and background check. He didn't bark, cry, or make a sound for an entire year. Then he became the boss off the yard. Terribly affectionate. If he sees anyone on his now shorter walkers, he starts wagging and rolls over and just wants to be touched Try not to think about losing your pet. Remember how happy your pet made you. Remember how happy he was because of you! Hang in there!
