Well, the pic is a little small so its hard to really see the ears, but to me it looks like there is a little difference in the way they sit. My suggestion would be to either take him to see one of the breeders or DT members near you and have them help you post them, or keep doing it yourself, but either way, keep them posted. I dont remember how old you said he was but I am pretty sure with them posted for a while he will stand. Its just going to take some persistence on your part, and for you to remember not to get discouraged. Any time you feel like giving up, come here and get some encouragement, but dont give up! Now, if you have been posting his ears and he's like, say 3 years old and they arent standing, well then I guess you could just accept they wont stand but give it a reasonable amount of time to work. When I unwrapped my girls ears after the first week they fell like they had never been cropped. So dint give up!
