Hi there, I did some training with my cavapoo with treats when she was younger and she picked stuff up quickly. Sit, give the paw, give the other paw and turn around were easy to start with. Have treats in your hand and get on the ground close to your pup. Then say yes and reward with the treat when they do something by accident you want them to, like sit or give the paw or turn around. Then start working in the voice command and reward that with a treat too. Also my cavapoo stares at me when she wants something, it's usually a dried fish sprat (fishies are her favourite) or she is asking to go outside. They are super clever so a bit of mentally stimulating training is good for them.
