I would strongly urge you to speak with a vet before supplementing with any vitamins or calcium. Most dog foods are completely balanced and it's not wise to upset the balance without consulting a vet first.
Too much calcium can cause growth retardation, kidney problems, and possibly deficiencies in other minerals like phosphorus, iron, and zinc.
What I did for Willie was use mole foam (for human feet) in his ear that flopped and that worked great for us. I had to tape it several times a day, since he would scratch it off, but it definitely was worth it.
Good Luck with those ears.
P.S. Even if they don't stand your baby will be beautiful!
Hee hee your doggies bed is very similar to cocos - cool! I noticed you said to watch what vitamins you give your doggie - oh no your making me panic i give coco conditioning tablets - she's fine on them - do you think it could be damaging her health?
Marcus got a bit of low fat yogurt every day for the extra calcium and it worked great plus he thought he was getting a real treat. I did this when his ears were first trying to stand and again when he started teething and they got a bit floppy.
