My small, 15-pound dog recently had a coyote attack her when she escaped into the front yard. While the coyote was scared off before it did serious damage, a small bite was taken and treated by the vet. However, before she was fully recovered, I gave her the play dead command, where she lay down then yelped in pain as her shoulder hit the ground. She now runs away every time I give her the play dead command. Though it has been several weeks since the attack, she won't evade me anymore, but still ignores me when I do the play dead command.
How can I re-train this command after her injury? (Command is finger gun and saying "bang!")
She knows what I want her to do, just refuses to obey. Other commands are fine.
