Poodle (Detailed Introduction)

　　It is often heard among pet-raising sisters that their Teddy dog's coat color becomes lighter and lighter, just like dyed hair fading after washing many times, which makes many Teddy owners quite distressed. So, what exactly causes the Teddy dog's coat color to lighten?
　　There are many reasons that cause the Teddy dog's coat to lighten. In general, it is quite normal for a puppy's coat color to change somewhat as it grows up, such as becoming lighter or a solid color turning into a patterned one.
　　First, due to genetic factors, even if the Teddy dog's parents have perfect coats, it does not guarantee that the puppy’s coat will not gradually lighten, nor does it guarantee 100% inheritance of the coat color to its offspring.
　　Second, seasonal changes also affect the Teddy dog's coat color. For example, comparing a Teddy dog in summer with one in winter, you may find that the summer dog's coat color is lighter than in winter.
　　Third, as the Teddy dog ages day by day, its coat will also gradually become lighter. From this point of view, the dog's coat color change should be considered a normal physiological phenomenon. Just like humans, as they age, their hair and beard color also gradually lighten, changing from black to white.
　　Finally, health and nutrition issues also impact the Teddy dog's coat color. When the dog is sick, lacking nutrition, or deficient in protein, vitamins, and other nutrients, the coat color will become duller, and the texture of the fur will also become rougher.
　　Nowadays, there are many pet products on the market, so coat lightening is no longer a problem. Pet stores have Teddy-specific coat-enhancing powder, fish liver oil, and other health products that show significant effects with long-term use. Eating animal offal also helps with coat lightening issues, but offal should not be consumed long term.
