Regrettably, I wasn't able to make contact with any local doggie business people while in Shanghai. The one new Kennel that I have arranged to visit didn't materialised because the business venture was called off. All I have is a couple of encounters on the streets with dog owners.
I met this lady walking her Spitz puppy "BAOBAO". Obviously Baobao is not trained, as he have difficulty obeying even a basic command such as 'SIT'. And I have to tell you it wasn't because of language barrier cos I do speaka his language lol, Mandarin. The lady owner actually offered to sell me her puppy for 800 yuan would you believe it! I kept telling her that I don't live in Shanghai but she kept up with her sales pitch and wouldn't listen.
I met this lady with her Toy Poodle at Yuyuan. It's comes naturally for me to connect with dog owners cos I am able to get the doggie's attention. This Toy Poodle named NANA showed off her "Paw" trick. A security personnel for the Shopping Complex kept warning her owner not to her dog out, as it is forbidden. That is China for you, still not very dog friendly in public places. However I am aware that there is already tremendous improvement.
