I am training my new puppy even now, he is almost 12 weeks old but he must learn to come back to Mom. I can't deprive my old lady of her free hunting trips and he is becoming too heavy in the (excellent !) sling. So after he gets his shots and can roam freely, he will need to 'come' when called.
Mine have all run free in the forest not too far from our home. We have a large garden and are practising recalls with the pup. He is very good already. Sometimes he gets a treat, but mostly just praise and a cuddle. He is ever hopeful of a treat though, so he comes back 'in case' !
He will also have to learn to walk on the lead. He is fine already but gets impatient when I stand still. This is something else we are practising -
Out in the woods he will at first go on a longer and longer (light weight) lead until I am sure of him. I don't like flexis but for a brief spell they can help.
There are few things as pleasurable as watching a Basenji at full speed - such elegance and grace !
Good luck !
