Hi and Welcome to YT!
So sorry for the loss of your cousin...
Put a treat, or a piece of kibble or chicken as close to her as you can get without upsetting her. Then walk away, and come back in a few minutes to see if she took the treat. Do that often throughout the day, eventually hide and watch her to see her come out. Stay longer after placing the treat and move away slower. Eventually she'll come out while you're there and take a treat from your hand.
Talk to her in a high pitched voice, or like babytalk. Some relax quicker with high pitched voices. Tell her it's okay, she's a good girl, and pat the floor in front of you.
Move slowly around her in the beginning. |
