A lot of you thought Penny would have resembled #2 as a puppy & Amber Mae was the only one to guess it correctly as a Rhodesian Ridgeback. They are known for the ridge of hair that runs down their back, but not all Ridgbacks have a Ridge.
They are much bigger than Penny (she's 45 lbs and RR females are generally in the 70-80 lb range).
There are definitely some facial similarities.
But Penny's personality is all Boxer as is her body type. Someone obviously wanted her to look like a Boxer because they had her tail docked & dewclaws removed. So we've always called her a Boxer Mix.
We're going to do the DNA test Gomer & Opie recently posted about in the fall & it should be interesting to see exactly what she really is!!!
