Here's what you should do:
* Consult your vet: The best way to determine the right kind of soap for your puppy is to ask your veterinarian. They can recommend a puppy-specific shampoo that is gentle and safe for their delicate skin.
* Use a puppy shampoo: Look for a shampoo specifically designed for puppies. These shampoos are formulated to be gentle and pH-balanced for their skin.
* Avoid harsh ingredients: Stay away from shampoos with fragrances, dyes, or harsh chemicals.
* Dilute the shampoo: Even puppy shampoo should be diluted with water before use.
* Avoid bathing too often: A puppy this young doesn't need frequent baths. Only bathe them when necessary, such as if they get particularly dirty.
Remember, it's always best to err on the side of caution when it comes to your puppy's health. If you're unsure about anything, consult your veterinarian.
