I know chis are at a higher degree than we are, so I just bathe mine in warm water. They are common for dry skin problems as well. Bathing them often could lead to skin issues. Once a week I will bathe mine with just conditioner and ever few weeks I will actually clean clean him.
Definitely don't bathe her too much as I am guilty of this with my own chi. A good moisturizing shampoo will help.
I rub the outside of my chi's ears with slightly soapy water and wipe it dry with a towel after. I also bathe mine in the sink ! Safer to go with a slightly cooler temperature that you are comfortable with, something lukewarm.
Miya may squirm a bit if she's never taken a bath but try to be calming an firm at the same time.
Same concept as bathing a baby really.
Warm water that is comfortable to the inside of your wrist.
make sure you don't get soap in the little eyes or water in the ears.
I don't use dog shampoo too many junky chemicals SLS (Sodium Lauryl Sulfate) & SLES (Sodium Laureth Sulfate) etc perfumes, brightners it's all in there! (If I won't put that garbage on my kids sure won't on my dogs!) We just use a natural shampoo from the health food store if you have a Whole foods nearby you would find something suitable there as well. Just read your ingredients.
Anyhow that's about it! or how we do it
You will find that it's the commercial products that dry the dogs skin out and cause irritation.. if you bathed your dog weekly or such in water or with a detergent free soap you would find that they don't get any skin ailments.
I bought an all natural sulfate-free organic puppy shampoo, it's expensive ($15 dollars for shampoo and $15 dollars for conditioner) but when I look at the ingredients in the back I can actually pronounce all of the ingredients. I haven't used it yet, but will when I get my pup, but i did smell it so far and it smells heavenly like citrus lavender! Mmmm!
