Its too cold to wash them anyways down here. Its winter lol
Even brushing everyday will strip the coat of all the natural oils that they need in their coat to keep them warm and dry. Tess has a natural shiny coat cos of the feed we give her (copra meal is good as well to make it shiny. The coconut oils in it helps) I don't care how shiny she is in the paddock cos, well, no one cares but if they are healthy, they will naturally have a nice coat that shows good health. I use the cheapo stuff at the moment and it is working ok. I buy both the shampoo and the conditioner for only $10 each. We will have to go horse shopping soon Rylee!
