We have a backpack but only cause he likes the bag 🤣 but if not he’d never be able to walk anywhere cause he’ll just run off 100mph and it’s just not safe 🙈
we only started using them recently, once my lb was confident on his feet. we brought the reins for holiday, and he loved being independent on the beach walking through the water. I didn't buy reins that look like a dog lead, I brought a colourful animal one (lion)
I use them for my daughter. She’s a runner and mostly refuses to hold my hand. She’s started to get a bit better with holding my hand but the reins definitely give her a bit more freedom. I use a backpack one so I’m not sure about other ones.
