Hair:
I use the Chris Christensen System on Adina. Day to Day shampoo and Conditioner and the Ice On Ice spray which is great with tangles and just a before you brush spray which I love (even tried it on myself and it works lol)

Teeth:
For her teeth I use the Pet Gel and the Pet Oral Hygiene Solution which you put in their water to help fight bad breath I like them both.

Skin:
I give her DermCaps 10 (For petite and Miniature Breeds) everyother day. It says on the bottle to give everyday at one pill per 10 lbs. so I give it to her everyother day since she is only 4 1/2 lbs. I get them at my vets but know they are online too. I have seen a great difference after 1 mon. of use.
Hope this helps a little
Smiles,
Myra
