If you have a trusted vet, call him or her. That person may be able to come to Blanca, rather than bringing Blanca to her. I would NOT try to do this yourself, not in any way. It would be too traumatic emotionally and physically. Call you vet. When s/he understands the situation, I am sure s/he will come up with a positive solution.

We will keep you, and Blanca, in our prayers.
