Can anyone tell me what kind of dog my dog is?

Could anyone help me figure out what breed mix my dog is?
Can you explain the reasoning behind your guess?

I would say she is a medium size dog between 45 and 50 lbs

Thanks

(Sorry in last pic she is just being silly)


Her mom was a purebred black labrador retriever, thats all we know. Not sure what the father was. Maybe some sort of hound I don't know. (my father owned the mom and this dog was the result of an accidental litter...good reason to always have your dogs spayed and neutered)

Shepherd/Lab would be my guess!

And here is my other one which I've asked about before but figured I'd put her up to just for fun.

It really doesn't matter what they are, its just fun to guess sometimes

This one all we know for sure is she is part Jack Russell Terrier and she is around 20lbs.....(I think she is 23lbs currently but she stays between 19 and 23lbs)
