Has anyone ever used the waterless dog shampoos? Do you have any recomendations or ones to avoid? Wassim could really use a bath but until his leg is fully healed from surgery that is not an option. He's getting a little greasy and I really hate not having a clean dog! His skin is also dry and flakey so it would be a bonus if I could find something that would condition his skin too. Any recomendations are welcome!
