well you guys may be need some old tricks
it is proven it works on my last normal dog(give away to friend already) and my current shih-Tzu.
1. prepare a bottle of pepper.
2. when your dog/puppy pooo, quickly put some pepper on it. not too much at least still allow some poo smell, because if put too much the pepper might cover the poo smell. but also not too little, because you need those pepper to give your dog nose some shock!
Too little will not work! It might encourage ur dogto eat more!
3. After apply on it, let her sniff the poo, (just imaging what will happen when yourself sniff pepper).Usually dog who eat poo will not require your assistant. They will automatically eat the poo. if your dog don't sniff it make him do that!( only do for the first, second time when you use this pepper only just to let him feel the power of pepper.
4.Remove his water also. Let him enjoy the pepper shock for a while. and start laughing......
5. repeat this by putting pepper on the poo....until one day he scare his own poo.
that time your dog will say: OMG!!! POO! Run! It will hurt my nose!
hahaha.
