If these hairs are not removed they will accumulate and eventually cut off air circulation to the skin. This can create many problems. A layer of dead hairs blocking air flow and create a moist environment that leads to a fungus infection of the skin. Additionally, skin can begin to dry out which can then lead to even more hairs falling out.
The Best Brush for Chihuahuas - For year round proper grooming, choose a quality slicker brush. For times of moderate to heavy shedding you will actually not want to technically use a brush, as a de-shedding tool or a rake will work best.
How to Brush -
The key is to NOT just skim over the top layer of fur. You will want to gently brush down through the coat, gently brushing down to the skin and then sweeping up and out. Work section by section and stop to remove hairs from the brush as they accumulate.
How Often -
it is recommended to give the coat a good brushing once a week; during heavy shed times (seasonal spring/summer shed & after heat cycles) 2 to 3 times per week may be necessary to keep up with the shedding hairs. It is recommended to choose a certain time of the day for this grooming element and others (dental care brushings, checking the nails, etc.)
Dogs have amazing internal time clocks and if an owner grooms their Chihuahua at a certain time each day, the puppy or dog often learns to relax while being brushed , knowing that it is time to do so.
