While humans have hair, dogs have fur. This is why many owners use the best
dog clippers to keep the coat of their dog smooth. If your dog is heavy and thick,
he may spend whole summers being uncomfortable and frustrated. Professional
dog clippers serve the need to trim your dog’s coat. This will make him/her more
comfortable. 
Most of the best professional dog clippers come under one of the below-
mentioned categories:
●    Single-speed dog clippers: They are the best option for novice users; do
not heat up as fast.
●    Variable-speed dog clippers: Its versatility is advanced; they are a better
tool for a perfect finish to dogs’ coats.
There are several characteristics and features you need to look at before selecting
the ones that suit you. They are listed below:

1. Motor’s speed and power: The best professional dog clippers usually
   offer high power and rotations per minute, but very rotary speed
   unavoidably generates more vibrations and noise. You need to search for
   dog clippers with the right balance between power and speed, along with
   noise, heat, and vibrations. There is also a high chance of blades heating up
   and an increase in vibrations. 
2. Corded and cordless clippers: Cordless dog clippers are indeed more
   convenient, but they need your focus on batteries. There is no right or
   wrong here; it’s about your convenience over power usage.
