Naomi I'm so sorry to read of the loss of your best friend. It's always been me that has to deal with such. I can assure you my lovely, it ain't easy. I still feel sad when I think of them. After all, they are members of the family. The Labrador we had when the boys were little was a star. They both learned to walk by holding his tail, which ended up looking like a Morris Minor starting handle. He put up with it all, he slept under their cot and always came to tell us if they were not sleeping peacefully. When they went out to play he went with them. Heaven help any adult, or other dog, that came too close to them!
Your wonderful elderly, rickety, potty pup, (they are always pups, aren't they!) will always be with you, in your mind and in your heart.
My deepest condolences to you. xxx
