How to get a really bad smell off my dog?
It sounds like you’re dog may have rubbed itself in fox or sheep poo. Fox especially has a very strong odour and takes a lot of washes to go. As your dog is a Rottweiler you prob can’t see it because of the dark hair. Wash her in tomato ketchup or tomato juice, or just make sure you scrub her everywhere with the shampoo to make sure you’ve clened the poo off.
