Ideally, you should aim for:
- **8 weeks old:** No more than 2 hours
- **3 months old:** Up to 4 hours
- **6 months old:** Up to 6 hours
- **1 year and older:** Up to 8 hours (but regular breaks are still essential)
Always ensure your puppy has had plenty of exercise and has had a chance to relieve themselves before being crated. Additionally, provide toys or safe chews to keep them occupied. Gradually increasing the time they spend in the crate can help them adjust and feel comfortable. Remember, a crate should never be used as a punishment, but rather as a safe space for your puppy.
