I have to disclose that I am a retailer of dog grooming products, but I do not sell all of my favorites.
For my full coat boys, my favorites:
1. Bio-Groom Oatmeal Shampoo and Silk Creme Rinse (conditioner)
2. Les Poochs Botanique Hypoallergenic Shampoo and Creme Rinse
3. Vellus Show Shampoo and Conditioner, Satin Cream (for conditioning and thickening topknots), and Anti-stat brush spray
4. Isle of Dogs Coature line
5. Pet Silk shampoos, conditioner, topknot gel, Silk Serum (my favorite product for detangling, although it is meant as a coat dressing).
And an arsenal of great brushes and combs.
