At that point, if you don't see it, you'll smell it. Dogs, on the other hand, aren't quite as compulsive in their grooming habits as cats and consequently often just need a bath. Apparently they think this fools potential 'prey' animals into thinking they're not a dog at all. If it is just that your dog has been rolling in something smelly or swimming in smelly water, a good bath should do the trick. Dr. Paul recommends bathing your canine companion with a mild shampoo made for dogs.
Skunks present a particularly stinky problem for dogs and their owners.
If your dog gets 'skunked,' you'll know about it and your neighbors will know about it for several weeks. The best solution is to dilute apple cider vinegar in water and pour it on your dog. Tomato juice works as well. There are also special pet products available to rid your dog of the skunk odor. Dogs are also well-known for their ability to cause quite a stench of their own.
