shampoo

I was in Arizona for 5 days and had a pet sitter taking care of the goats. I come back yesterday evening to find the minerals feeder empty, and 4 goats with dandruff. 3 babies and their mom. One of the babies has really, really bad dandruff that goes all the way from the base of his neck to...

We clipped our fair goats last night and I noticed fleas on them. Can I use a medicated dog shampoo on them, or can I put Tea Tree/Citronella oil on them? Or is there something I need to use to get rid of the fleas and keep the other bugs from biting them now that they are shaved?
