Good morning dog lovers in the house, my 3 months old rotweiller didn't want to run around like it used to do normally, this morning, after feeding, the dog ate well and is very active, then I tried to walk it with a chain on it's neck for the first time, but instead, it was crawling and won't run around like it normally does, perhaps, it could be scared of the chain, pls I need insight from people who could clear me on this.... Thanks in advance

Change the chain.put belt around his neck for sometimes,then try it again.
