My aussie has dropped her coat as she is not heavy boned I brush the coat up on her legs but as she has dropped her coat the hair is very flat any suggestion, hoping someone will come up with an idea I haven't thought of.

Its a bitch thing... Moult = no coat = no shows for 6 weeks then.. wait for it.... A Season usually follows !! Nothing weill put coat back or make a shed coat on a longer coated breed look any good in my opinion. You just have to wait and let nature do its thing. Plush puppy do a coat volumizer that may help a little bit.

Chirs Christensen Bottoms Up coat lifter can help to some extent
