When potty training puppy pick puppy up & carry outside. After 2nd week puppy should be basically potty trained, then you can put puppy on harness & leash to walk out. If you don't know puppy schedule by end of 1st week please contact us for help. Easier to help create good habit then to wait 3 more weeks & have to break a now bad habit.
We now only use collars for holding the puppy name/phone # tag. We recommend harness & soft sided leash for potty training due to it allows for control over puppy entire body instead of just neck which can get damaged by collar if pulled on. this was verified by vet & trainer
Keeping in mind puppy is new to collar, harness & leash training. In order to help get puppy used to both harness & leash we recommend letting puppy run around house while wearing them. This allows puppy to get used to the feel & weight of both harness & leash other then just outside pottying.
