What should i do i have a Lab and she used to fetch and now she just looks at the toy and wont fetch?

It's possible that your Lab has lost interest in fetching due to boredom or lack of motivation. Try using a high-value toy or treat to encourage her to engage with the game again. You can also vary the environment by playing in different locations or introducing new toys. Lastly, consider short, positive training sessions to rekindle her enthusiasm for fetching.
