It’s been about eight weeks since I found a lump in the back of the Brindle Dog’s left thigh that is almost certainly a mast cell tumour.
The tumour grows a bit, and then shrinks suddenly as it releases histamines, heparin, and proteolytic enzymes (which break down proteins) into her system. Eventually, as the tumour grows and more of these substances are occasionally released all at once, she might start getting allergic reactions, stomach ulcers, and other damage.

My then-partner and I were advised to send her to Saskatchewan for a month of radiation treatment during which time she would be fostered, undergo general anaesthetic every day for the radiation treatment, and require intravaenous feeding because her throat would be burned from the radiation. We elected not to do this. Continue reading
