Hi. My dog Beau is 6 months as of the 26th of this month. I'm starting to worry his ears may not come up on their own. The have been up, down, sidways and just about every other position since about 3 1/2 months. In the past week they have made progress though. Should I intervene now or wait a week or so since they seem to be doing better. Also, he was a late teether if that matters any.
