Train the pet to Sit Down

Kneel besides the seated puppy, by holding its collar with one hand and place a treat by its noise. Slid his front paws forward while pressing gently in his shoulders until hi is in his down position. Say 'down' when he is in down position and keep him with your hand on his shoulder for few minutes. Repeat the command 'down' once again. Praise him and he will soon know that you want him to do.
