When we got our new pits we went to PetSmart and got the Halti’s. They are wonderful. We took them inside WalMart and with no prior training, when we stopped they sat. Walked nicely beside us. Had no problems. WalMart will let you bring your dogs, all you have to say is they are service animals. Sociaizes them and gets them used to a lot of people. There service animals can be for mental illnesses to. Like an autistic child, depression…etc. We had a pit mix, which we had to put to sleep, but anytime I would get up and my bloodpressure would drop she would stand in front of me and not let me move until I wasn’t dizzy anymore. They are the most amazing animals. Trully are in tune with you!
