Dying from Cancer ☹️🐶

I found out today that my beloved family dog (staff) of 15 years has Cancer and she's dying a painful death. She has a tumour the size of a football and it breaks my heart every time I look at her 💔😭.  The Vet said there is no treatment for her as she's too ol+it's so aggressive and growing at such a fast pace, our only option is to have her put down because keeping her alive is too painful for her. ☹️☹️☹️☹️
