Hi, C.j.W
Yes we traditionally use the pelt of a dog in Tongbei.
There is few way to use it in the video I use the head but some use the back, actually it depend of which gong-fa that you will practice.
There are two big reasons that we use pelt:
-we use the pelt because it has a kind of oil which is good for the hand.
- The skin is a kind of like human skin.
The skin should not be too dry, mine is old, and in Europe I won’t use it ha-ha
I’m thinking to make more serious video about tongbei and gong-fa in future, wish you enjoyed it;-)
Have a nice day
