Why Do Dogs Shed?

Of all the reasons people love dogs, shedding isn't one of them.
They make good companions, they can be valiant protectors, they are incredible listeners, but one of the drawbacks of owning a dog is that they shed. No matter how fastidious you are about keeping your house clean, it's nearly impossible to keep up with all the fur.All Dogs Shed
Due to the nature of the way a dog's hair grows, all dogs shed to some extent. New hair comes in, the outer root sheath attaches, the hair goes through a resting phase, and then it falls out. But the average life span of the hair varies from dog to dog.Many Factors Impact Shedding
Poodles have a reputation as a breed that doesn't shed. That's not really true; they do shed. But since their fur grows continuously and each individual hair has a longer life than most other breeds, they don't lose fur as frequently, so it goes largely unnoticed. The change of seasons can also prompt shedding. Most dogs have not only the top coat that you see and feel, but also an undercoat of shorter, softer hair. This undercoat changes with the seasons. In the spring, the heavy winter undercoat falls out to make way for the lighter summer undercoat. In fall, the summer undercoat comes out to allow for the heavy winder undercoat. Seasonal shedding is prompted by both temperature changes and the natural shortening and lengthening of days throughout the seasons. Dogs that typically spend a lot of time outside are more likely to be susceptible to seasonal shedding, especially if they are a breed with a naturally thick undercoat.
