Then why are you here? Do you have a Chin or atleast a hedgies? Since you are a dog trainer would you mind telling me more about wifi dog fence? Is it a good alternative to a traditional fence? How does the shock system work?

This is an old thread, feel free to browse it maybe you will be able to find what you are looking for.
Just like any other animals it takes time for Chin to adopt on his new environment. Give it some time and always keep an eye on him. Let me guess, you named him Goku because you are a fan of Dragon Ball Z?
If you can't find a quality and safe feeder in a local pet store, you might as well try to go to Amazon wherein you can find an extensive list of the said product.
I think he is still in the process of himself be familiar in his new environment. There has been a big shift after you guys have adopted him. It surely takes some time for an animal to feel secure in his new home.
It is indeed a helpful post, I just recently adopted a Shih Tzu, and he leaves all his mess on our kitchen tiles. I have tried to ask the former owner if she has ever conducted a potty training but she failed to do so as she has tons of dogs at home.
