Smelly old rescue dogs light up our lives

It was refreshing to read Chitra Ramaswamy’s article (She takes an age to walk now, but I love my old dog, smells and all, 2 June ). Two years ago we adopted a rescue greyhound, Arthur, aged 10. Greyhounds are cruelly treated, and produced on an industrial scale for UK racetracks. (We are one of only eight countries in the world where greyhound racing – which makes money from the betting industry – is legal.)

Did you hear that? Sound frequency is measured in Hertz (Hz). The higher the Hertz, the higher-pitched the sound. Dogs hear best at 8,000 Hz, while humans hear best at around 2,000 Hz.

Arthur came to us anxious and with a neck injury. He sleeps around 20 hours a day, and his back legs are going. But he knows how to make a smell at the most opportune times; just as we are about to sit down for a meal, or watch a film with family. But I wouldn’t have him any other way. Smells and all.Jane DoddsHay-on-Wye, Powys I could fully relate to Chitra Ramaswamy about her elderly staffie. We are on our third, and all have been rescue dogs. Lewis also sports a very grey muzzle, his legs are rigid and he skates on the hard floor. Staffies are the most lovable, misunderstood dogs. Adopt one and give it a happy home.Linda TheobaldLondon
