DOG FAQ - What are the differences between the smooth coats and the long coats?

The issue of whether or not there is a difference in personality seems to be a topic of debate within the Chihuahua community. Some claim that there is no difference in personality; others swear that longcoats have a tendency to be "soft-tempered" while smoothcoats are more prone to aggressive behaviour. Let's set aside the personality issue and focus on physical and maintenance differences.

Smoothcoats tend to have coats that are much coarser than longcoats -- almost like bristles in some cases. Smoothcoats also shed more than longcoats. However, longcoats can shed as well. Heavily coated longhairs require brushing about once a month, but this can be a pleasureable exercise for both Chihuahuas and master rather than a chore.

As far as bathing is concerned, as a general rule, the longcoats will need to be bathed more frequently, and it'll be a longer process (both washing and drying). The bib -- the furry part of the chest -- can easily get irty and matted. Longcoats can also occasionally get fecal matter stuck on their "pants." You'll have to either bathe your dog or cut the bit off with scissors when this happens.

Some Chihuahua owners swear by long-hairs and wouldn't have anything else; it is as much a matter of personal taste as is coat color.
