Hi, new here, and doing some training with my boy Barney who is 2, and was a lockdown dog through circumstances. He's doing shorter walks at moment, to bring on his loose lead walking, which is coming on, as well as techniques to try to stop him lurching towards vans and bikes,that he often reacts too. We are working with Trainer. He isn't getting as much freedom off lead in the park because of this training, so trying to do stimulating games for him in the house, as he sometimes needs this to stop boredom barking. Any tips welcome. Thanks.
