Adopted an Abandoned Pup

We found this sweet girl after a neighbor had moved away and left her behind because they didn’t want to deal with a sick pup. Turns out she had parvo and was so close to death; on the second morning we had her she was completely limp and unresponsive. Was at the vet for hours and spent my emergency savings🥲 She’s now doing better and is a little ray of sunshine! She has extreme separation anxiety, so my fiancé and I have decided to keep her to avoid any further trauma. We named her Zemi :) However, we can’t figure out what she is for the life of us. The vet said she could be a collie/shiba mix, but I don’t get shiba at all from her. She looks like a little coyote haha. Any ideas?
