I got the same problem...
Since I got Astra, my other dogs are a mess!
She is not 10 months and still no progress. Little devil love to wrestle and also climb on the other dogs in a dominant way.
My 2 other girls need way more grooming to stay nice now. And I have finally shave down Tom Pouce ,a schnauzer cut like my other male Teddy.
Hope she'll come down as she age!
So sorry I got no advices for you...
Just get ready for A LOT of brushing!!
