While dogs can sleep under air conditioning, it's important to ensure they are not exposed to excessively cold temperatures for extended periods. Air conditioning can lower the temperature significantly, and some breeds may be more sensitive to cold. Watching for signs of discomfort, such as shivering or seeking warmer areas, is key.

Humidity levels may also drop in air-conditioned environments, potentially leading to dehydration. Ensure your dog has access to fresh water and check if they are staying properly hydrated. Always provide them a comfortable and cozy space where they can move if they feel too cold.
