She's only just 20 weeks and is a chihuahua cross so very tiny (and very wilful).
I am obviously following a training schedule and she does sit and has reasonable recall, except when she's on the lead where she just decides to go in the wrong direction.
I'm terrified of her injuring herself, she just has a normal leather collar and an extendable lead.
Would a harness be better? She only weighs about 2kg so it's not a problem with her pulling me, it's more me pulling her when she goes the wrong way.
Any advice welcome.
