To find the best brush to easily groom your dog, you need to know that dogs have different grooming needs depending of their coat. Some have short hair, some have long hair, and some have undercoats. The different types of fur have different needs for brushing and grooming.
Done correctly, you can lower the amount your dog sheds by 85%. For instance, brushing after a bath can remove much more hair than just brushing alone.
If you’re like me, you want your pup to enjoy themselves as much as possible. With my Golden Retriever Nola, that means that she needs to be groomed often because she goes swimming nearly every day.
There is more on brushes for dog grooming at Wikipedia and this page has some further information on dog grooming.

SheddingTools
Shedding tools can come in the form of a brush with closely-spaced, stainless steel tines that work on removing the undercoat or a shedding blade with serrated teeth. I use a Furminator to remove undercoat fur. Things have improved a bit so I’m recommending a newer model here.
