Regular grooming is vital to keeping older pets cool and comfortable during hot months. Removing dead fur through brushing helps in better air circulation around their skin, reducing overheating. For dogs, a summer trim (not too short to avoid sunburn) can be beneficial. Cooling baths can also offer relief, but it's crucial to ensure they're dried properly to prevent chills. For pets that don't bathe, like certain small animals, providing a dust bath or wiping them down with a damp cloth can help manage heat. Always ensure grooming sessions are gentle, as senior pets may have sensitive skin.
