As for the female,if notix is not helping, try bathing her with Balfo Shampoo (Bayer) n rub in balfo powder. If it doesn't help, after bathing her wash her with Ridd mixed in water. This should help..it has helped me n have repeated it within a week. But if it doesn't take her to vet asap..maybe he'l give Ivermectine shot.
As for pups, cant say as they are too young. Talk to a vet asap.
