I have a repeat client who I have been watching their dog most weekends for the last few months. I already give her a discounted rate for longer stays of $25/night instead of $32/night. She will be leaving for a month and wants a larger discount. I have tried to explain to her that I do not feel comfortable going further down in price ($25/night is basically $1/hour if broken town.). How should I explain to her that I cannot go lower than $25/night?

I provide daycare for an intact shih tzu and he smells disgusting. I have tried to give him a bath and he still stinks after. I think the stench may be related to the fact that he is not neutered but I'm not sure. How should I tell the owner that I can not continue caring for him because his odor makes me physically nauseous.
