You are welcome. Train him "Drop it!" - he should drop it at your feet, and "Give it!" - he should give it into your hand as exchange for a tiny piece of Cheddar (or any treat he likes). Please, don't forget, that a ball play is interaction, it is a play of two. Toys represent prey for dogs. If you threw it high - that is a small bird, if you threw it like in bowling and it runs in short bounces - it would represent a mouse. Ask him "Sit", "Down", "Come", or any other command and treat by throwing his ball for him, thus the ball becomes a sort of a treat. Further in training, if you place the ball at your armpit or simply hold it in your right hand and start walking - that is the way to start training him "Heel".
