A deaf dog has struck up an adorable friendship with a hearing-impaired volunteer - and they communicate through SIGN LANGUAGE. <br /><br />Phoebe Curtis, 18, has trained five-year-old crossbreed Lollie how to sit, lie down and raise her paws by using hand signals. <br /><br />The pooch has been with the Dogs Trust rehoming centre in Evesham, Worcs., since June, and it was feared that her deafness would put off potential adopters.
