Hi,
It's effective. I had use it with my baby(a golden ret) when he had flea. Add a little amount of vinegar and mix with water and it will do the trick. You have to let it soak within five minutes and rinse thoroughly. Just remember to be always gentle to her as she is just a pup and still a bit fragile. Also, you might want to put the mixture on a spray bottle and spray all over your house where fleas might live. Because there's a possibility that they will come back if there are some fleas left in your house. Just to make sure.
