Recall - how to practise
Getting your dog to come to you. Use a long rope or lead and attach it to your dog. Let your dog go and do its own thing, then when it doesnt expect it, call your dog to you and reel your dog in. Lots of praising your dog when they do come to you and sit in front of you. Allow your dog to move off again, and when they least expect it, call them to you and reel them in again if you need to. If and when they come to you and sit in front of you, lots of praise again! Make it really exciting that they come to you and listen to you.
Always follow through with your dog when you ask them to do something.
