What do you think she might be mixed with?

She looks like a Labrador Retriever mix. I do see some Rhodesian Ridgeback, too. I can tell she is part Pembroke Welsh Corgi, too. Australian Cattle Dog is definitely possible. But, the RR (Rhodesian Ridgeback) is very obvious. You can see it in her face. The ridge is a dead giveaway, too! lol Her color does look like that of a light colored RR.
