Teddy dogs can usually be trained in two or three months. They can be properly trained to defecate, shake hands, stand and other simple instructions, but the training time should not be too long.
Sandy can officially start training when she is five or six months old. You can lure her with food, train her to turn around, bow, jump, grab and other skills, and reward her with food when she makes corresponding actions.
Teddy's IQ is so high that he can usually remember it after teaching it for about five times. However, he still needs to strengthen training in peacetime to avoid forgetting the password for a long time, which leads to slow response.
