Can anyone tell me about the Minksheen shampoo? I was told that it helps with the ticks and fleas. Is that true? Found two ticks on Rosie today.

I am not a happy camper. I hate to buy the Advantix if I can find something else that works. But I will if I need to. They have changed from Advantix I to Advantix II and I don't know the difference. I am hesitate to buy without knowing what has changed.
If you have any information please share. And if you know where I can get it. I was told Amazon. Does any YT member sell it?
