Hi, I have an 11 month old sheltie male who was in an accident and consequently had to wear an e collar for 7 weeks while his leg healed. He had perfect stand-up with 1/4 tipped ears prior to the collar and now his ears are further apart and one is flopped--hound-like. Is it too late to get them back to where they were? Also, he was great about ear cleaning before but has become more and more reluctant to have his ears touched, caressed or cleaned since. He is clear of infection--had him checked. Advice?
