If it's Teddy,
Both kinds of combs are needed.
The needle comb has a large area and is used to comb dead hair.
The comb device is used for styling after combing the hair with a needle.
Because the hair after needle combing is too fluffy
The dog's hairstyle is not very good.
So both kinds of combs are needed.
If your dog's hair is shorter than Teddy's.
I suggest you only buy a needle comb.
