German Shepherd Puppys Ears

Question
Well I have a German Shepherd that I got when he was 6 months. His ears were a down and floppy as a GS mix mutt's. I was told that Supposedly one of his ears were seen up before but I also heard that where he came from, the kids played and pulled on his ears. I heard that's not good for them and can damage muscles in the ear. The people that I got him from kept saying that they csn't guarantee that his ears will go up and that made me concerned. His ears are pretty wide so I was afraid it wouldn't come up. Also I was told that he may have 10% or less wolf in him so I wondered if that played a role. Well anyway, at about 7 months old I saw a technique online about using tear mender (you can get it at walgreens for about $4 or $5) to glue the edges of the ears together (by the way, the product and idea is great). After the glue wore off, I noticed his ears were not sticking out more to the side resembling mary poppin's hat. lol. Well I also notice that when I take him for walks, when he's playing, or when he holds his head down his ears stand up. It  may stand anywhere from 5-15 seconds. I get happy when I see that but then a little discouraged when it goes down again. What I want to know is....is this a sign that his ears will go up? One is stronger than the other. I can see a "dent" in the bottom of one (which makes that ear lay sideways over the head then eventually back down again). I guess he is still teething because he likes to chew on a very durable real bone he has. I don't know how long he will be teething ans if when he is done if his ears are supposed to harden or not. So do you think it's a definite yes?? And by him being almost 8 months old and 65lbs should I give him calcium supplements? Thank you!!

Answer
Don't give him calcium supplements.  Almost all of his calories should be coming from a commercial dog chow.  If so, he is getting all the calcium he needs, and in the right ratio to phosphorus.  Adding calcium to such a diet would only mess up the careful balance and actually interfere with the body's ability to absorb what it needs.  The dog guide school I raise puppies for forbids giving them anything except their dog chow.  they breed hundreds of dogs every year and X-Ray them all at a year old.  There is no better source of info on producing sound dogs.  None of the alternative diet people have the sort of proof of their methods the dog guide school has.

He should have all his teeth, but his jaws are still developing, and he does need chew toys.  I am glad you mentioned sturdy ones.  

I have little on the ears.  Most of the dog guide school's Shepherds have their ears up early, and they don't worry about the ones that don't.  I haven't seen anything showing the gluing and taping helps.  Since the ears often come up on their own later, any improvement from it may have happened anyways.  With the control they have over their ears, it may even be behavior.  Try praising him when you see the ears up.
