His grooming is unique and not a traditional poodle style, but he’s still adorable. I think the mustache with the shaved ears looks a little terrier-like.
Good news….. yes they will definitely grow back. Bad news it will take almost a year before they are truly long, probably 8-9 months when they start to look more what you want. Don’t worry about the in between phase because that looks cute as it’s growing out. It won’t look awkward.
At one year of age he’s probably going through coat change which can mean lots of mats and tangles developing quickly, including 10 seconds after a complete combing to the skin. You might have brushed through and not had any problems but you might not have been aware there were mats near the skin. The last time I had a puppy poodle was decades ago and I had forgotten how bad coat change can be… it’s deceptively sneaky. when my puppy Theo started into coat change I put him in a German clip with shaved ears to make coat change easy for both of us. I found the area just behind the ears was the worst.
You and the groomer may have been correct. You may not have noticed mats that the groomer found. Groomers hate to untangle mats, it’s time consuming and they don’t have time because they have more dogs to groom on their schedule. Its a shame she didn’t call you to let you know there was a problem and she would shave the ears.
I happen to love the shaved ear look, poodles look like baby lambs or llamas. I’m keeping my puppy in the German clip…the one with a carrot tail, not the shaved version. It’s very easy to take care of and I think stylish. Several members here on PF have their dogs in this clip. Also take a look at Twyla’s Mr.Leonard Pink. He has adorable shaved ears with a groom that similar to your boy’s but with a shaved face and beard. For future grooms, while your boy’s ears grow out you might want to consider the German or Twyla’s style to make your boy look like a poodle and that the shaved ears were a deliberate choice.
