I have a German Shepherd, put some fleas,tiks ,then I gave him a bath with shampoo for dog's and then I put that liquid that I did the first time,now he's got like dandruff

It's from the medicine. He should be fine after his next bath with regular conditioning dog shampoo. Just dont donit how. The medicine needs to work.

I always google home remedies first, I find a lot of good ideas on there! My Dog had dry itchy skin and I found an oatmeal bath recipe to use and his skin, fur it worked beautifully! Good luck

I have had that issue. Their skin geys dried out. There are sprays that help moisturize their skin.
