Do dogs eat less in summer
Yes, many dogs naturally eat a little less in warm weather. It’s perfectly normal.
Research shows dogs often eat more in colder months, when they burn more calories keeping warm.
Why do dogs lose their appetite in summer
In hot weather, dogs need less energy to stay warm. They’re also less active, often choosing a shady snooze over a long run.
Less activity + less calorie need = smaller appetite.
Should I feed my dog less in summer
If your dog is regularly leaving food, try reducing their portion by around 10-15% at each meal.
Stick to their usual balanced diet (such as our RAW POWER meals or MIGHTY MINCE). Avoid switching foods just to tempt them to eat more.
If you’re concerned about weight loss, check with your vet first.
Will eating less mean my dog loses weight
Not usually. Dogs burn fewer calories in summer, so a smaller intake should balance out.
But it’s smart to keep an eye on their weight. Use these simple checks:
-
Ribs: You should feel ribs under a light layer of fat, not sharp bones.
-
Waist: From above, your dog should have a slight waist.
-
Abdomen: Side view should show a gentle tuck-up behind the ribs.
-
Spine and pelvis: You should feel but not see the bones.
If your dog is otherwise happy and active, a mild drop in appetite is fine. But if you also notice:
- Lethargy
- Vomiting
- Diarrhoea
- Noticeable weight loss
- No interest in food or treats
— contact your vet.
How to keep your dog cool and comfortable over the summer
Here are easy ways to help your dog stay cool:
-
Walk at cooler times: Early morning or evening is best.
-
Offer shade: Indoors or outdoors.
-
Provide water: Fresh bowls, topped up often. Some dogs love ice cubes or frozen bone broth (dog-safe and salt-free).
-
Cooling treats: Try frozen fruit like blueberries or homemade dog-safe yoghurt cubes.
-
Sunscreen: Use dog-safe sunscreen on light skin (nose, ears).
-
Limit car trips: Cars can get dangerously hot. Never leave your dog in a parked car.
Why does my dog get diarrhoea in the sun
Diarrhoea is more common in hot weather. Possible causes include:
- Overheating
- Dehydration
- Changes in routine
- Intestinal parasites (more common in summer)
If your dog has ongoing diarrhoea, or seems unwell, always check with your vet.
Final thought
It’s normal for dogs to eat a little less in summer. Keep portions balanced, offer cool spaces and plenty of fresh water, and enjoy your summer walks together.
And after a hot day, why not treat your dog to a refreshing RAW POWER meal or tasty MIGHTY MINCE?
Stay cool and happy munching!
