hi, my border terrier cross is missing from his home in lincolnshire, he has been gone since this morning. he is 6 years old but has a little bit of white on his muzzle, he did the same thing last year and got parvo, we had to pay 800 pounds for the vet, and he nearly died! :'( he has got a blue colar on and he is tagged. please help, i miss him real bad and i have been crying all day.
