Spitz is a family of northern dog types rather than a single breed. The fox-like face, small upright ears, thick double coat and plumed tail curled over the back come from cold-climate ancestors, and the label stretches from Pomeranian-sized dogs to Keeshond-sized ones. Dogs listed as Spitz are often white or cream, frequently resemble American Eskimo Dogs, Japanese Spitz or German Spitz mixes, and usually weigh between 10 and 50 pounds.
Most are alert, loyal and quick to bark, and many stay reserved with strangers. San Diego's mild winters make a cold-weather coat more than enough, so the main care points here are regular brushing, heavy seasonal shedding and keeping the dog cool in late summer. Expect a dog that bonds closely and likes having a job, even if that job is watching the street.
