3 puppies we left on the side of the road, starving and covered in fleas. We kept the only girl and everybody thinks she is something different. I have heard Pitt bull, beagle, Shepherd, and everything in between.
It's hard to tell with a young puppy, especially if they are a mixed breed. She looks like she has some Lab Retriever or Jack Russell terrier in her though, and possible Staffordshire Bull Terrier as well (but not purebred)
