 What is shedding?

Shedding is a process that generally happens in dogs with a lot of furs. When the hairs in the fur of dogs start to lose their identity it is known as shedding. Chihuahuas may lose all of their hair in the process of shedding. It is harmful to the health of dogs and may also lead to baldness around some regions of the body. This can sometimes become serious and the beautiful dog may lose all of its furs if proper care is not given. The owner of the chihuahua must catch the signs of shedding and take proper action against his dog. There is also a variant of dog breeds where there are no or very fewer hairs.

Why my chihuahua sheds

The reason why chihuahuas shed is to have a new coat that can be more protective. The coat also helps the dog to regulate the internal body temperature. It contains Keratin(a type of protein) and dead skin cells. The dog’s body maintains a constant temperature, which is around 101-1002.5 degrees °F. In order to adjust their body temperature dogs depend on some special means.

Therefore, in order to cool off, The first thing dogs do is limit their physical activities, then lie down and pant. Also, to stay snug the dog will bring down the metabolic rate, lying in a sunny spot as you may notice a lot of dogs do. Or they hide under a blanket.

The role of a chihuahua’s coat is to help him stay cool or warm. The thickness of the coat is a crucial factor. In other words, chihuahua may possess a thicker coat during the cold seasons and a thinner one during the hot seasons. The thicker coat prevents the heat from getting away from a dog’s body, this way he stays warm. While the thin coat decreases the rate of heat absorption to keep chihuahuas cool.

Who sheds more, long-coat or smooth-coat chihuahua?

Logic will push you to think that long-coat chihuahuas shed more than the other variant, however, this is not the case all the time. For example, a smooth-coat chihuahua with an undercoat will necessarily shed less than a long-coat chihuahua without an undercoat. Even if some long-coat chihuahuas have only a top coat, most of them have two coats.

long-coat Chihuahuas often shed their hair in clumps, making it easier to clean up.

Moreover, long-coat chihuahuas always shed their hair in small masses which makes it easier for the owner to clean up.

Shedding schedule of Chihuahua

There is a difference in the timing of shedding between double-coated chihuahuas and single-coat. While the majority of double-coated chihuahuas shed their coat twice per year( once in spring and again in late autumn), and their top coat progressively during the year. On the other hand, single-coat chihuahuas are Shed in spring or by degrees throughout the year. 

The benefit of shedding in spring is to develop a lighter and thinner coat while shedding in autumn develops a heavier and thicker coat. However, there are cases when a dog sheds all his coat in a limited period of time, this phenomenon is called “blowing a coat”.Moreover, your chihuahua regardless of its coat type(single or double-coat) will be Shed all the year.

This schedule is not a constant rule, it is possible that your chihuahua will shed once or twice per year, or even throughout the year progressively.

The Shedding Cycle

All mammals including humans and dogs have a 4- stage cycle for growing and shedding hair. They are:

  1. Anagen: it is the phase of growing the hair, the blood which is rich in nutrients stimulates hair growth.
  2. Catagen: the phase when the hair will stop growing as the hair follicle separates from the papilla.
  3. Telogen: the phase that comes before the hair is falling out.
  4. Exogen: the phase when the hair is shedding.

After the fourth phase, the cycle is repeating itself. 

Below is an illustration that shows the shedding cycle.

How light of the day Affects Shedding

Until now we know that shedding is related to seasonal temperature. However, the biological process of shedding is provoked by daylight variations.

Just like humans dogs also have what we call circadian rhythm, and it’s their biological clock. The circadian rhythm controls the physical activities and mental and behavioral changes that react to light and darkness. While the circadian rhythm tells the dogs when to sleep, it tells them also when to shed. In addition, shedding is affected by the amount of light in the day. 

The amount of daylight or what is known as a photoperiod regulates the amount of melatonin that a chihuahua’s pineal gland produces. Melatonin can control a lot of things, it can trigger mood, body rhythms, and shedding. The difference in daylight in seasons impacts the production of melatonin, therefore deciding when a chihuahua sheds his coat and when to grow a new one.
