       Currently, the world's methods for classifying dogs include natural classification, purpose-based classification, show dog classification, and body size classification. Among these, body size classification is the most commonly used method in daily life. As the name implies, this method classifies dogs solely based on their body size, regardless of other factors. According to the body size classification, dogs can be divided into five categories: toy dogs, small dogs, medium dogs, large dogs, and giant dogs.

Weight

Height

Characteristics

Breeds

Toy Dogs

<4kg

<25cm

Very small body size, cherished by many and sometimes called "pocket dogs." It should be especially noted that the care and management of this type of dog can be more complicated.

Chihuahua, Yorkshire Terrier (detailed introduction), Pomeranian, etc.

Small Dogs

<10kg

<40cm

Small dogs are usually lively and cheerful; some dogs can be somewhat noisy. Their barking is loud, leading many people to think such dogs are fierce, but most of them only bark loudly out of fear or anxiety.

Shih Tzu, Papillon, etc.

Medium Dogs

10-30kg

40-60cm

Medium dogs are quieter than small dogs. With proper training, they can become reliable guards. However, training this type of dog requires a male trainer, as many women may not be able to handle the intense play or sports activities. Additionally, dogs of medium size or larger should not be raised freely to prevent injuries.

Bulldog, Chow Chow, etc.

Large Dogs

30-40kg

60-70cm

Large dogs have strong learning abilities, so many are trained as working dogs. Well-known guide dogs come from this category. However, training large dogs requires specialized guidance from professionals.

German Shepherd, Labrador Retriever, etc.

Giant Dogs

>40kg

>70cm

The largest body size with a strong deterrent effect. Giant dogs require strict management to avoid frightening or harming others.

Tibetan Mastiff (detailed introduction), Great Pyrenees, Afghan Hound, etc.
