[Xena Rio's Mum]

Went to the vets yesterday and Xena has been put on a course of Prednisolone combined with Aktivait. She seems to be taking very short breaths at the moment but it does not seem to be affecting her wanting to go for walks. Has anyone else had breathing problems in any of their dogs with cancer. Also does anyone know which is the best diet to feed her. I can't give her masses amounts of protein as she has a slight problem with her kidneys. Any help whatsoever would be greatly appreciated.
