I don't show my dogs very often, but I use Bio-Groom's Protein Lanolin Shampoo or Bio-Groom's Natural Oatmeal Shampoo. As a conditioner I use Bio-Groom's Super Cream or Bio-Groom's Vita Oil.
There are so many different shampoo and conditioner; I guess there are some other good brands as well. :)
Kriszta,
this is NOT grooming, this is what people pay a lot of money of, called "peeling" :-) in Germany....
it can be done this way, too: first they take a nice bath (here it's Lake Constance) and then they roll in the grass. Much softer on skin and coat
and if you want you can add some yellow pollen from dandelion, helps with soft coat, I can tell :-)
but if you do it right they will finally look like this again:
sorry, we are not really serious, but with Beardies one can't be serious all the time!
Have a nice weekend, here we have a holiday on Monday: Whitsunday weekend
my daughter - who is a bigger expert in beauty-business - told the same about peeling (actually she told Daze that they all had a "girlish" day with peeling, solarium and aquafitness)
a bit more seriously, this is what I brought from the Crufts (as none of these products can be purchased here in Hungary) and I can tell you, all work fine on my dogs.
