Well, she is such a crazy head that i wouldnt be able to hold her if i use other collar... never gets tired, even after 20km of walking

Its harmless, just the dog is not pulling forward so much. And i flip it to the other side when we are walking in the woods, just in case some wild beast appear and try to bite her neck - i have small wood house in the woods away from civilization
Oh and btw its small 70 litres aquarium... wish i had space for 70 galon hehe :P
P.S. the wood house is just for vacations, i dont live there
