I haven't used that, but LOVE Cowboy Magic available through Amazon. Our dogs are in water all of the time. I generally keep their bodies naked (using either a 7 blade or a 10 blade), but like to leave hair on their head and the back of the neck. Between water work and playing, we are always fight matts. Cowboy Magic is GREAT!
if you like cowboy magic another great one is Carr Day Martin Mane and Tail- it's basically cowboy magic in spray form so not as much on your hands- LOVE It has more of oa conditioner built into it then cowboy magic as well
I used 5 gallons worth of D-Mat. I used it primarily on shedding coats to release deas, shedding hair such as on goldens, newfies, pekes and poms. I do not like it on curly coars like poodles or bichons, nor do I like it on drop-coated dogs. I have moved on to 2 different conditioners....Natures Specialties Anti Shed for shedders and Les Pooch for all other fou fou dogs.
I started using my daughter's horse "Mane and Tail" as a conditioner and it seems to help with the mats issue for quite a while after the bath, rinse and dry. I also heard somewhere that "Show Sheen" mixed with 3 parts water in a spray bottle works well for mats too. I figure if Show Sheen can allow me to comb burrs out of a mane or tail it probably will work on mats but honestly I haven't tried it yet.
