Excellent To Remove Airedale Terrier Undercoat
348278
The Mars 20 X-Fine Coat King works wonder on an Airdale Terrier. The Mars Coat King helps remove and thin out the soft undercoat in record time. Removing the dead undercoat truly speeds up the hand stipping process.  The specialty retailers that carry this item charge an arm and a leg.  Amazon by far has the best price for this item.

Perfect for taking out the undercoat of our long haired pups and leaving the top coat in tack. We have had to buzz our long haired pups every summer due to them not being able to shed their undercoat and so they would over heat in the AZ summers. Now we can brush out their undercoat and leave their top coat so they can stay even cooler than when we use to buzz them. Love that it is made specifically for our dogs breeds as well. Great product and it came quickly and was packaged nicely. The price is really good too, better than what we found in the pet shops near us.

It works great to de-tangle and get the undercoat out. The curved style of the brush makes it gentle on the dogs skin.

This is a great product as it is easy to remove the pet hair right from the brush with a push of a button, rather than try to drag it out with your fingers or a comb.  Still the teeth are long enough to deal with my thick coated cats.  Very pleased with this purchase as it has made the job of grooming much easier

Definitely removes undercoat.  Still a good bit of pulling required, so you have to hold your dog's hide to help reduce stress.  Wanted something that would just cut the matts out painlessly, but I guess that doesn't exist.  My dog HATES getting combed....

I wish I could give this thing seven stars, but five will have to do. I was able to pull entire sheets of undercoat out of our husky without disturbing the topcoat. I've never had anything work so well.  It's even easier to keep the fur pile together. The fur stays clumped, instead of getting spread out and floating around like with the blade style furminator. This thing really digs the loose stuff out so much faster and easier.  Check the photo to see what 20 minutes will get you.

Read the directions, leave it on the animal as required, rinse. No more scratching! Good stuff for our once itchy terrier.

The Furminator tool was all that I was expecting to remove the under layer of fur from my cat.  You must take your time but it is well worth the effort.  This is especially helpful of a dense coat.

Lightweight and easy to use. Really gets the undercoat fur pulled out and off my husky! Stops me from constantly picking at the tufts of fur that can stick out without good brushing

Great to use under my dogs eyes. Does a good job of getting the crud off.

I have 3 labs and I've tried all sorts of brushes, but this one really works for the undercoat. It removes so much fur. It's time consuming though, but I'm not sure any other brush would be faster. This brush really works and is gentle, or at least my dogs don't seem to mind it at all. I recommend this brush and think it's well worth the money. It's well made and does the job.

This is mostly an under coat grooming tool. It pulls out the thin, fine fur under the top waterproof coat. If your dog doesn't have an undercoat, it is not the right tool for your dog! That being said, I really like how this brush gets the under coat out. It's great in the cooler seasons. I usually pair it with a metal loop brush for the over coat. It did really well with dematting the fur around my dog's collar. He had some light matts and tangles around his neck when we first adopted him and regular brushing with this tool keeps them away. He has a medium length coat.

As a professional groomer I love this tool.  It works best on long coated shedding dogs like Golden Retrievers, Collies, even German Shepards.  Not really effective on Boston Terriers, Pugs, or Labs.  Short coats and non-shedding coats need a different tool.  I use this to pull out undercoats and to diminish lines left by my grooming tools.  I would be lost without this tool, I use it more then the furminator tool.

This is a great tool to get fur and undercoat out.  My dog is a Cavalier Spaniel Corgi mix.  She sure does have lots of hair and undercoat.
This tool is great!  The dog likes it and we like it even more.  You sure can't go wrong for the price and we've recommended it to the people where we take her to doggy daycare once a week to play with other dogs.  They were very interested since we told them how well it works.  You sure can't go wrong with this tool.  I'm so glad I bought it and would recommend it to others.

We're currently using this to de-shed my German Shepherd's winter coat and it is working wonderfully! It pulls the thick undercoat out and she is looking about 10lbs lighter. We filled two walmart bags full of hair, so it is certainly working well!

I'm giving it 5 stars, not because it's the best tool for all pet grooming needs, but because it is just as good as the Furminator and other, more expensive products, possibly a little better designed (ergonomically), and it doesn't cut the topcoat, which is really important. You won't be disappointed with this product. I use it on my double coated cowdogs (a BC/Catahoula/Aussie mix and a hangin tree cowdog). Both dogs have thick undercoats and slick overcoats. This tool works perfectly.

The Zampa pet grooming tool works really well on both my 25 lb. Wheaton Terrier (long wavy hair) and 12 lb. Italian Greyhound (short straight hair).  The dogs don't seem to mind getting brushed at all and it takes out a lot of fur, especially on the Wheaton.  It works much better than the wire brush I used to use.  It leaves their fur soft and light and cuts down on finding stray hairballs in the house.

Its very easy to use.  Simply pull it in the same direction of the dogs fur and then remove the hair from the brush by pushing the ejector button.  It works very well.

It seems nicely made and has a good handle.

All in all a wonderful dog brush.
