My GSD is 13. He is severely arthritic and in the past year has lost proper control of his hind legs. Today he refused to eat and only ate a treat. He is not able to stand at all. I have been using the sling and he can normally walk once propped up but today he can't walk at all even after I lift him up. He takes Deramax and supplements. I am afraid what will happen to him if he can't get up at all. Would he get bed sores? Has anyone had a similar experience? We have no vet in the area who will come home to check out on him and I do not know how I can take him to the vet if he can't move at all. It is so sad to see him like this.
