I have 2 pieces of advice.
Chicken. That is the treat I could always get Maggie to eat. Boiled chicken breast or chicken jerky. Maggie is not a fan of many treats either.
Walks. Walking stimulates them to go. Take some chicken with you and take a walk. It will be good for both of you. As soon as she goes tell her "good potty outside" or some phrase you choose and give it to her. AS SOON AS SHE GOES. She has to associate the treat withe action.
Hopefully she will love the chicken so you can try this. If she doesn't want to go on the leash the treat can help with that too. |
