I had been given the advice of putting cayenne pepper on my puppy's poop. He did not eat his brother's only his own. Now the cayenne pepper did not work for him obviously a mexican
. Try doing that I trained him by using the word LEAVE IT now he could careless. When walking both dogs and there is poop I started when he first came to me with the word leave it as he did not have any shots yet and I had been concerned for his health. Hope this works
