My dog tizzy. Healthy all her life has now developed a tumour in her respitory system. If untreated she may die. She is so distressed and unhappy. I cannot afford the investigation procedures, let alone the impending surgery and or treatment.

I can tell bare to see her in pain and discomfort like this. She is only 8 and half her expected age.

Please help.
