Hi Lynn,
An important "tool" to consider is a grooming table! One for use with small dogs shouldn't be too expensive. Dogs are much more cooperative for brushing when they are on a raised table. Winnie climbs right up onto my table (with the help of a step stool). Lots of praise and treats will make them want to get in line for brushing.
Bring your brushes into the groomer next time and have the groomer evaluate your equipment. They might have some suggestions (specific to your dogs' coats and cuts) as to what you should use, and some groomers sell brushes and combs in their store front. My favorite brush is the Chris Christensen "T Brush" it is a pin brush that is shaped like a slicker. It comes with pins of two different lengths, 16mm and 27mm. The pins are polished on the ends that contact your dog's skin, so they are not sharp. I've tried MANY brushes before this one, and I can assure you this one is the one my dog likes the most. (and I like it too)
Also ask your groomer to recommend a finishing spray/conditioner you can use while brushing. Spraying (a little) before brushing will help prevent damage to your dogs' coats, and will make brushing easier. I've used the Best Shot Ultra Vitalizing Mist, and the Chris Christensen Ice on Ice, with equal results. I'm currently using the Ice on ice because it is fragrance free, and that is a good thing for therapy dog visits, as clients could potentially have a reaction to fragrances.
I've never tried the Emu Oil shampoo or conditioner, so I cannot comment on that. If your dogs are getting bathed weekly, I wouldn't see the need for more bathing.
