Dog Eating Less Food in summer : During the summer season a dog’s appetite or the amount of food it eats decreases compared to normal. let me tell you this is normal to a certain extent. When a dog eats food any food heat is generated in its body. In the winter season, this heat helps keep the body warm. However in the summer the environmental temperature is already high, so the body doesn’t need extra heat. As a result the dog feels restless and this leads to a reduction in food intake. The dog eats much less than it normally would.

So, if your dog has reduced its food intake slightly there’s no need to panic it’s normal during the summer season. As I mentioned, digestion generates heat in the body, which contributes to this behavior.

Thermoregulation in Dogs /Dog Eating Less Food in summer
Another reason for reduced appetite is that the heat generated in the body during digestion doesn’t dissipate easily in summer. In humans we sweat through sweat glands to cool down However, dogs don’t have sweat glands like humans. They only have sweat glands on their paw pads and a little around their nostrils. Instead dogs rely on panting to regulate their body temperature which you may have observed they pant with their tongues out. In veterinary terms this is called panting and it’s their primary method of thermoregulation.
For those who are first-time dog owners this behavior might seem alarming especially if your dog is panting heavily. But for experienced pet owners this is normal and they understand that panting is more frequent in summer. However new pet owners might get scared thinking, “Why is my dog panting so much?” Friends there’s no need to worry this is completely normal.
Key Takeaways So Far
By now, you should understand two things:
- If your dog is eating slightly less than usual, there’s no need to worry—it’s normal in summer.
- If your dog is panting heavily with its tongue out, this is also normal as it’s their way of cooling down.
What to Do If Your Dog’s Appetite Decreases Significantly/Dog Eating Less Food in summer
Now let’s say you feel your dog has drastically reduced its food intake. What should you do? Just like humans drink cold drinks, lassi, mango juice or other refreshing beverages in summer to regulate body temperature you might want to offer similar cooling foods to your dog.
Cooling Foods for Dogs
In summer, feed your dog foods that are cooled down. For example:
- Fruits: Watermelon, papaya, or mango (which are in season) can be given in small amounts. Peel the fruit cut it into small pieces, or even mash it for easier consumption. Dogs often eat mashed fruits more readily. remove the seeds and rind, and then feed it to your dog.
- Avoid Hot Food: Don’t give your dog hot food. Cool it down or refrigerate it briefly before serving, as this makes it more appealing.
- Curd or Buttermilk: Include curd or buttermilk (locally called mattha) in your dog’s diet. These are cooling and help with hydration.
Reducing Non-Vegetarian Foods
We all know dogs love non-vegetarian foods like chicken but in summer reduce the amount of chicken or other meats. Meat generates more heat during digestion which can make your dog uncomfortable and reduce its appetite further. Instead increase the intake of vegetables, fruits, and curd to lower heat generation and keep the digestive system comfortable.
Hydration is Key
Ensure your dog drinks plenty of water. Chilled water is better and adding ice cubes to the water bowl can make it more appealing. Dogs are more likely to drink chilled water which helps prevent dehydration. You can also offer ice cubes directly dogs often enjoy licking them, which helps with hydration.
Ice Cream as a Treat
As a treat, you can give your dog a small amount of vanilla-flavored ice cream. Avoid chocolate or other flavors, as they can be harmful to dogs.
Electrolytes for Hydration
If your dog is showing signs of dehydration or eating very little, you can mix Glucon-D or an electrolyte powder in water, as per the instructions on the packet. Use this solution to make ice cubes and offer them to your dog periodically. Ensure the solution is used within 24 hours to avoid spoilage. This will help replenish electrolytes and prevent dehydration.
Adjust Feeding Schedule
Instead of feeding your dog three to four times a day divide the same amount of food into smaller, more frequent meals (e.g., five to six times). This reduces the heat generated during digestion and makes it easier for your dog to eat without feeling overwhelmed.
Additional Tips
- Grooming: If your dog has long fur, it may feel hotter. Consider getting a haircut to help keep it cool.
- Deworming and Vaccination: Ensure your dog is up-to-date on deworming and vaccinations. For more details on deworming, watch my previous video, where I’ve explained when and how to deworm. Regular vet checkups are crucial.
- Obesity: Keep your dog’s weight in check, as obesity can lead to health issues, including reduced appetite.
When to Visit a Vet For Dog Eating Less Food in summer
If your dog completely stops eating, refuses ice cubes or other foods, and appears lethargic, don’t experiment with home remedies. Take your dog to the nearest veterinary healthcare center immediately. Playing with your dog’s health is not advisable. If the dog is eating a little less, you can try the tips mentioned above, but if it stops eating entirely, consult a vet promptly.
Dog Eating Less Food in summer Summary
In summary, feed your dog cooled foods in small portions, include curd and fruits, reduce non-vegetarian foods, and ensure proper hydration with chilled water or ice cubes. These steps will help your dog eat better and stay comfortable in the summer.
