Wahl USA Pet Friendly Waterless No Rinse Shampoo for Animals - Coconut Lime Verbena Scent – Oatmeal Formula Cleans, Conditions, Detangles & Moisturizes Dogs Fur – 7.1 Oz - Model 820015A

Our vet recommended this waterless shampoo when our dog was really afraid of the bath, and like others have said we keep Earth Wipes or similar around for quick clean ups/traveling. You could possibly put some of the waterless shampoo on a cloth and wipe some areas, but stay far, far away from the spay. The smell will fade on its own as well. https://www.amazon.com/Friendly-No-Rinse-Waterless-Shampoo-Coconut/dp/B00GZQYLOE
