There are many different breeds of pet goats. Some people want large goats and some people want small goats. Some prefer floppy ears and others like them perky. But regardless of what characteristics you are looking for in a pet goat there is no doubt that you have many options.

The American LaMancha was bred in Oregon but the roots of the breed goes back to Spain. These goats are easily recognized by their extremely short ear pinnae.
