So I'm pretty sure the dog has fleas due to the non-stop scratching although when I look closely through her black and white fur, I can't see anything.
I've tried the dropper twice, two weeks apart as recommended, and bathed her in flea shampoo, but she's still scratching like a demon.
Although I've had dogs before, they all managed to avoid fleas. Can anyone advise next steps? Should I try the tablets? Or is it vet time?
