Our old girl passed away last night

Blaze was 12 yrs old & 1 of the best dogs I've ever had. She was so gentle with everyone from the day we rescued her. We didn't even realise she was sick til her dinner time yesterday. Found out she had an aggressive form of cancer in her spleen which spread to her other organs & she was bleeding internally also. Took her into emergency bout 11pm & said our final goodbyes bout 2am. We know she's not in pain anymore, but we're devastated about losing her so suddenly
