Here's why:
* Dog skin is slightly acidic: Unlike human skin, which has a pH of about 5.5, dog skin is slightly more alkaline, ranging from 6.5 to 7.5.
* Maintaining the acid mantle: This slight acidity is essential for maintaining the skin's protective barrier, known as the acid mantle. The acid mantle helps prevent infection and keeps the skin healthy.
* Avoiding irritation: Shampoos with a pH too high or too low can disrupt the acid mantle, leading to dryness, irritation, and even skin infections.
Important Note:
* Puppy shampoo: Puppies have delicate skin and may need a shampoo with a slightly lower pH (around 6).
* Special needs: Dogs with skin conditions may require shampoos with specific pH levels recommended by their veterinarian.
Always check the pH level of your dog shampoo and choose one that is appropriate for your dog's age, skin type, and condition.
