Discounts for major life event: thoughts?

My youngest dog has been diagnosed with cancer and needs a 3k surgery. I can't work a "normal" job due to a disability so I do a lot of pet and house sitting. My pet sitting rates are the lowest in my area, but I'm thinking of taking more off so that I can hopefully get more clients and afford her surgery. As a community of petsitters, what are your thoughts on this?
