Opinions on Shepherd mix's ears standing up
My puppy is a foundling and so I don't know the breeds of his parents. Two different vets said he's German Shepherd mixed with either Bernese Mountain dog or Rott (possibly both or more). He's estimated to be about 4 old months right now and i've read it can take even up to 5 or 6 months for his ears to stand. After researching and looking at a lot of photos, I think he looks mostly Shepherd and would like it if his ears stood up (although i'll love him either way). He's definitely still in the teething phase, so I know I may have to just be patient and wait until that's over to find out, but I'd like some input.Could I get some opinions on whether or not his ears look like they'll go up?
(sorry, I know the photo is small, 2nd photo is from a few weeks ago, first one with him alert is more recent)
Also, does anyone know of any GS/Bernese mixes that have ears that stand?
