Help save my girl from euthanasia

About a year ago I adopted out 2 of my dogs because I had no means of caring for them. I found a friend whom I believed would be a great fit for the 2 and he sent pictures and kept me updated on and off for the last year. It was great.

This morning I got a call from chula vista animal care facility in California about one of the two. They had, had her for about a month. I was horrified and immediately asked about the brother. They called me back about 4 hours later and told me he had been euthanized early this morning. I broke down while working and for the last 8 hours have frantically worked on way to get to California from Washington to save Navi the sister of the Euthanized dog Deku.

I am I desperate need of any help I can get.

If anyone can help please let me know.
