What to feed your dog in summer: hydration, safe treats, and foods to avoid
Hot weather changes how much water your dog needs and which snacks are safe. Keep the regular diet steady and focus on water, timing, and picnic hazards.
Keep the main diet consistent
Most healthy adult dogs do not need a special "summer food." Sudden diet changes can upset digestion, so keep feeding a complete and balanced diet appropriate for age and health. Active dogs that exercise less in the heat may need smaller portions; ask your veterinarian before changing amounts.
Make fresh water the priority
Provide clean, cool water at all times, indoors and outdoors, and refresh it often. Carry water and a bowl on walks and car trips. Shade and frequent water breaks are part of heat safety; never leave a dog in a parked car.
Summer treats that are generally safe
Small portions of plain, seedless watermelon, blueberries, or cucumber can be refreshing treats for many dogs. Frozen treats should be plain and xylitol-free. Treats should stay a small share of daily calories, and new foods should be introduced gradually.
Barbecue and picnic foods to avoid
Keep dogs away from grapes and raisins, onions, garlic, chocolate, alcohol, xylitol-sweetened foods, cooked bones, corn cobs, fatty trimmings, and skewers. These foods can cause poisoning or blockages. If your dog eats something dangerous, call your veterinarian or the ASPCA Animal Poison Control Center right away.
Know the signs of heat stress
Heavy panting, drooling, weakness, vomiting, or collapse can signal heatstroke, which is an emergency. Move your dog to shade, offer water, and contact a veterinarian immediately. Feeding cannot prevent heatstroke; limiting exertion in hot weather does.
