Grooming your small dog at home should not take a whole lot of time and is easy to do. You can groom your small dog in your kitchen sink or even in some bathroom sinks. Once he is bathed, you can dry him off fairly easily with a towel, brush him down, and even clip his fur with clippers or scissors rather quickly because of his size.
Taking care of your small dog at home is a simple task if you have the time to stay on top of it. Be sure when you are grooming your small dog at home that you bathe him on a regular basis, brush him as often as you can--especially if he has long fur and an undercoat--clip his nails, and take care of general maintenance things such as brushing his teeth and keeping the interior of his ears nice and clean to avoid ear mites and infections.
Some small dogs cannot stay still long enough to take a bath. If your small dog is one of those high-energy guys, consider bathing him in a nice warm bath just before bedtime at the end of the day when he's nice and tired. Be sure to end every grooming session with a treat and keep your grooming sessions at regular intervals so they are expected by your small dog.
