I just started using it and my baby is on Frontline.  I have not had any problems.  I really loved the shampoo.  A little bit goes a long way...not like the shampoo I was using before, where I would need a handful to get a small amount of bubbles.  It smells great and it left my baby's short hair (Chihuahua) super soft for a good week.  When I get a Yorkie, I'm going to use it on her hair as well.        |
