Hertzko Self Cleaning Slicker Brush for Pets - Large Slide Button Dog and Cat Grooming Brush with Retractable Bristles - Deshedding Comb for Long and Short Hair - Purple

Brush is big enough for my GR.

This is not the main brush for the Maine Coone because too big to do all the nooks and crannies, or even just under the chin. But it is great for 'finishing' i.e. collecting loose hairs, and it really does the job. Very solid and the mechanism works great. The cat purrs and loves it - not true for some others that are cheaper but just break and/or annoy the cat so he runs away if he sees them.

Works great for my fluffy aussie, doesnt pull. He likes it, wont get the undercoat, but picks up loose hair and tangles

We have 2 Great Pyrenees and both hate being brushed. We use the slick in addition to a comb and a rake. The previous slicker we used did not have any knobs at the end of the teeth on the brush and my dogs hated that brush, but it works so well on their long double coats. I caught my hand with the brush a few times and drew blood so I knew I needed another style. I picked this one since it has the little knobs at the end of the teeth, so it will be more forgiving against the skin. I liked the idea of the self cleaning brush. On the previous brush I would run the comb through it to remove the fur. With this brush, the button can be a little hard to engage/disengage. You slide the button forward and back. When it's empty it moves ok, but when you have fur in the brush it only slides back to a point and you need to pull the fur out of the brush to completely retract the teeth. This is fine for me and certainly makes cleaning the brush easier. The size of the head is nice and large so it is great for larger dogs. The head is very think though to allow the teeth to retract. This makes the brush feel a little clunky, but otherwise pretty comfortable in the hand. The teeth themselves are flexible, which helps prevent scratching the skin, but I've noticed some of them are bent in the wrong direction, so I'm not sure how well the brush will hold up over time. Overall it's a decent purchase. My dogs still hate being brushed but that is a work in progress.

My puppy didn't like this at first as it's so much more efficient than the one I've been using. I left it for a few days then tried again after using her usual brush and she was happier. Now I use it all the time and her thick fluffy hair looks stunning. Easy to clean too, push the button and the bristles disappear leaving just the pet hair behind.
