Barney is my remaining furbaby and my best friend, unfortunately His sister passed away last year, He is 13 years old and has been unwell for the past 6 weeks, he has had every test he can have but nothing was found, so now he needs scans and x-rays which I can't afford as I am a pensioner and live on my pension weekly. He has a cough which is not subsiding, this is worrying me greatly .because his sister died of lung cancer, but I won't give up on him until I have no other choice, any help would be greatly appreciated. Thank you for reading my request.
