My 4 week old puppy is infested with fleas, it even has nest eggs under fur.I want to know if i delute the hartz 2in1 flea shampoo can i use it on him. He's a large puppy look to be 8 weeks old.I want to shampoo the rug with that also in the room that he's been and also shampoo my other two big dogs with full strength. How will that effect the puppy?
I recommend that you use Advantage. This is the safest way to treat the problem. I also recommend that you use flea spray or bombs in the areas around the house the puppy has been. I do not which shampoo you are talking about but many shampoos are too strong for puppies. vetcare
