In his book, Talking Dogs, Sam Mason continues:

‘During the last couple of years of his life, Tigger, one of our dearly loved Italian greyhounds, gradually lost his sight. He’d developed cataracts. They robbed him of his vision, but they couldn’t steal his precious relationship with his masters. My wife Carol often referred to Tigger as her “lovey-dovey boy”. He would stand (not sit!) on our laps, putting his paws on either side of our necks, then affectionately tuck his head under our chins. It was adorable. Blind though he was, Tigger’s desire for the ones he could no longer see was unaffected. In spite of the cataracts that blurred our features, somehow he still managed to look us in the face. His diminished capacities may have hampered his movements, but his love and trust towards his masters remained rock solid. All of us who have placed our trust in the Lord possess handicaps… even spiritual ones. Do we use them as excuses for not pursuing God as intensely as we ought? Do we allow these hindrances to ration our love for Him? Or do we, with God’s help, find the strength to reach past our limitations to experience the unbounded joy of His presence, and fulfil the calling He’s placed on our lives? Yes, we may sometimes grope about in darkness every now and then, even stumbling and falling. But we can trust the One who understands our seasons of blindness. We can open our hearts to His love and love Him back… sight unseen!’
