Are Dog Breeds Capitalized in Writing?
Dog breed capitalization can be tricky because different writing styles have different rules. However, a simple way to remember is:
- Capitalize breed names that include a proper noun, such as “German Shepherd” or “Labrador Retriever.”
- Do not use capital letters for common nouns like “poodle” or “beagle.”
The confusion mainly arises because different style guides like AP Style and the Chicago Manual of Style follow separate rules. If you’re a pet writer, a dog lover, or simply someone who wants to write correctly, knowing the right way to capitalize dog breeds can enhance your writing’s credibility and professionalism. Misuse of capitalization may lead to inconsistencies and lower the quality of your content.
For example, some people mistakenly capitalize all breed names, while others keep everything lowercase, which is incorrect according to style guides. Understanding the specific rules for AP and CMOS styles will help you write correctly across different platforms. Let’s explore their guidelines so you can avoid common mistakes and improve your grammar skills when discussing your favorite dog breeds.

Are Dog Breeds Capitalized AP Style?
According to AP Style (Associated Press Stylebook):
- Only capitalize the proper noun part of the breed name while keeping the generic noun lowercase.
- Examples:
- German shepherd
- Labrador retriever
- Yorkshire terrier
- dachshund
- schnauzer
This approach prioritizes simplicity and consistency, ensuring that words like “shepherd” and “retriever” remain lowercase. AP Style is commonly used in journalistic writing, newspapers, and media publications. Following this rule keeps writing clear and avoids unnecessary capitalization, which can make text look cluttered.
For instance, “German Shepherd” may seem correct to some, but in AP Style, “shepherd” is treated as a general noun, just like “dog” or “cat.” This style guide focuses on readability, so even widely recognized breeds like “golden retriever” and “bulldog” remain lowercase unless they contain a proper noun. By sticking to AP Style, writers maintain consistency across articles, blogs, and news stories.
If you’re writing for online publications, sticking to AP Style ensures clarity and professionalism. Remember to always cross-check breed names in the official AP Stylebook to avoid errors. Consistency in capitalization helps establish authority and credibility in your writing.
Are Dog Breeds Capitalized Chicago Manual of Style?
The Chicago Manual of Style (CMOS) follows a different approach:
- Capitalize the entire breed name if it includes a proper noun.
- Examples:
- German Shepherd
- Labrador Retriever
- Yorkshire Terrier
- Dachshund
- Schnauzer
Unlike AP Style, CMOS treats breed names as formal terms, meaning that both the proper noun and the associated noun are capitalized together. This approach is often used in academic, literary, and formal writing, where capitalization emphasizes the breed’s distinct identity.
For instance, under CMOS guidelines, “Labrador Retriever” is fully capitalized, recognizing “Retriever” as part of the breed’s official name. This makes CMOS an ideal choice for books, research papers, and documents that require a more traditional and structured presentation.
While CMOS is widely used in professional publishing, it’s important to remain consistent with the style guide you’re following. If you’re writing for a publication that adheres to CMOS, ensure all breed names containing proper nouns are fully capitalized to maintain accuracy and readability.
