Dogs are famous for enjoying the simple things in life - notably chasing cats and eating meat. But that\'s not the case for unfortunate Joey, a dog who is allergic to cats, meat, and pretty much everything else except potatoes and porridge. Joey, an Alsatian-Collie crossbreed, gets a nasty rash if he eats meat or chases a cat. His allergy is also brought out by activities as diverse as running through grass or jumping into water. Now his owners, Lisa McCormack and Scott Muirhead, feed him a diet of nothing but potatoes and porridge - as they\'re the only things they\'ve found he isn\'t allergic to. Mr Muirhead said: \'Joey was consistently breaking out in boils and sores and we were scratching our heads over why. After a year of trips to the vets we finally got a special blood test performed to see what was going on. \'Our local vets were baffled,\' he added. \'They had never seen anything like it in a dog before.\' They now hope that a treatment of antibiotics combined with specialised dog food will help Joey avoid his allergies. \' He\'s looking much better,\' said Miss McCormack.
