FURminator Deshedding Tool
Probably The Best Grooming Tool In The World
If you have never used one of these before then the FURminator will be an absolute revelation.
This is the large 4" version that I use for all dogs and cats. The small ones do not appear to have the same feel or control.
Brilliant for both long and short haired dogs. The same in somewhere like Pets at Home will normally cost in excess of £36.00
