NB:the contents of parameters should corroborate reliably sourced information from the article, no information should be included in the infobox that is not covered in the article and there should be no requirement to add citations to the information.
name: Name of the breed (or landrace, crossbreed, hybrid, etc.). Should agree with article title (aside from any parenthetical disambiguation).
There is also image2 with corresponding parameters.
image_alt: Alternate text to describe an image to those that cannot see it.
If an image is included, alt text should be provided using image_alt. Alt text should not repeat the caption; instead, it should describe the image to someone who can't see it (see WP:ALT).
image_caption: A caption that describes the image.
altname: Other names by which the breed is known by English speakers.
kc_name: The name of the national kennel club of the breed’s country of origin
Link to a article if it exists then pipe the club’s acronym
There is also a kc2_name and kc3_name if more than one country claims the breed.
kc_std: The URL to the breed standard from that kennel club(s).
fcistd: If the breed is recognised by the FCI, add the URL to the FCI breed standard.
notes: Free-form concise comments, usually about the breed recognition or standards.
notrecognised=yes or notrecognized=yes: Shows a "Not recognis(z)ed by any major kennel club.
extinct=yes: Shows an "Extinct" message. This parameter should be removed if not used.
Special parameter
trinomial=: Replaces domestic dog with custom text. Italics and wikilinks must be done manually in the supplied parameter value. Entirely wild populations like the Australian dingo, use {{Taxobox}}, not {{Infobox dog breed}}. This parameter should not be used with |x=. If in the future we need to indicate a dingo-and-something-else hybrid that is actually treated as a dog breed, we can use |trinomial= for this, or change the template.
The microformat is created by the use of class="biota", and classes for individual taxonomic ranks, such as class="domain" in a span around {{{domain}}} (full list). Please do not change or remove those classes other than as part of development of the microformat. For background information, see microformats on Wikipedia and the microformat specification.
