Land Shark Identification

Hey yall, I went to my local APA to adopt a puppy but they sent me home with this!!! She’s gotta be some sort of dinosaur/ shark/ alligator by how sharp her teeth are😅 Any guesses on what breed she may be? Shelter said “Terrier mix” (in my area that means some pittie variant) but she has these cookies n cream spots that scream blue heeler to me. She also has webbed feet (all four), front dew claws, is ~20lbs at 4months old, and will actually bite me in the heels randomly 😂

Gonna get a dna test soon just wanted to have some fun and share my pretty girl 🤗

EDIT: First and last picture are most recent 2nd is closer to when we adopted her. She was around 3lbs then
