Budget tip: Finding the reason why your dog is leaving food and making adjustments as needed keeps your buddy healthy and your wallet happy. It may take a bit of sleuthing to discover the reason, but it’s worth it. Even a visit to the vet or a pet behaviorist to solve an issue before it becomes a major problem is always money well spent.
Why Is My Dog Not Finishing Food? (Quick Answer)
There are normally a few reasons why your dog doesn’t finish his food. The main reasons are:
- Overfeeding
- Too many treats
- Changes in routine or added stress
- Picky eating habits
- Bored with food
- Upset stomach
- Dental or health issues
Generally, if your dog only occasionally skips a meal or leaves food behind, I’m not concerned. But if a decreased appetite is new and lasts for more than 24 hours with other symptoms, it’s time to call the vet.
When a Dog Not Finishing Food Is Usually Not Serious
Your dog might be simply being a dog. If your pup is behaving normally except for not finishing regular meals, it’s probably not a serious issue. Make sure your buddy is:
- Acting normally with everything else
- Drinking water as usual
- Still excited for treats
- Potty habits are normal
- Only occasionally skipping meals
When It’s Normal for a Dog to Leave Food Behind
Some dogs are obsessed with food. But other dogs might be more toy-driven.
My dog, Henry, will never overeat. When he’s full, he walks away. Although if there’s a cookie, he won’t turn his back on it.
There can be other times when you may notice your dog not finishing food.
- Change in daily activity level. Henry always cleans his food bowl when he’s gone on a big hike.
- Age can decrease your dog’s willingness to finish his food. Senior dogs may develop a reduced appetite naturally.
- Weather can impact your dog’s appetite. Henry eats more in the winter than during the summer.
While it may give you pause to see your pup not eating all of his food, it can be perfectly normal.
Think about how much food you eat or don’t eat when it’s hot or when you’ve worked in the yard all day.
The same is true for your furry buddy.
9 Common Reasons Your Dog Isn’t Finishing Their Food
There are a few common reasons that will cause your dog to not finish his food.
1. Overfeeding Your Dog
If you are not measuring your dog’s food, it can be easy to put out too much or even too little.
Simple Fix: Measure your dog’s food carefully. This could even save you money.
The simple and easy act of accidentally overfeeding your dog can cause a multitude of issues. Explore them all and learn how to fix the problem in this article.
2. Too Many Treats or Table Scraps
If your furry friend is used to getting table scraps or treats upon demand, then he knows there might be a yummier option than what’s in his regular dog food bowl.
When I adopted Henry, I quickly learned that his original family fed him from the table. It took about a month to get him to eat from his bowl. Henry is stubborn, but I quickly learned I had to be even more stubborn. Those eyes are tough to refuse.
Simple Fix: Count how many cookies your dog can get during the day. For Henry, it’s one. Then make sure your family doesn’t go over the limit. Avoiding table scraps is a good idea to prevent a fussy eater. Although giving your dog human food, such as a plain carrot or a cookie, in his bowl away from the table is fine.
Just like your mom told you, too many cookies can ruin your dog’s dinner.
3. Your Dog Is A Picky Eater
If you are always switching food or offering your dog something different, your furry friend can become a picky eater.
He may simply hold out until what he views as yucky brussel sprouts are replaced by an award-winning hamburger.
Yep, your dog is often a furry kid. So, you may need to gently introduce food to your pup.
Simple Fix: I know this one is tough, but you really do have to become more stubborn than your dog. Henry held out for a while when I adopted him, but he eventually learned there would be no table scraps and ate from his dog bowl.
There can be many reasons your dog is a picky eater. This article explores them all and how to fix them.
4. Stress or Changes in Your Dog’s Routine
Every dog will respond to stress and shifts in their environment differently. When Henry is having an anxiety attack, he won’t eat much until he’s settled down.
I generally will give him a calm cookie, his heartbeat toy, and his crate covered.
Your dog can pick up on changes in his environment and will generally react in one way or another.
Dogs are famously sensitive to changes in their routine. Consistency of a regular routine is comforting for your dog.
Henry always tells me when it’s dinner time. It’s routine for him to eat at 5 p.m.
Changes to your dog’s environment can include:
- A new baby, spouse, or visitor
- Moving to a new home
- Loss of a furry or human family member
- New smells or sounds
- Rearranged furniture
Simple Fix: Evaluate if there have been any stress triggers for your dog. A calm cookie, like the ones I use for Henry, can help. But if you can’t figure out why your dog has anxiety and your vet has ruled out medical issues, call an animal behaviorist. They are skilled at getting to the root cause of your dog and offering realistic solutions.
5. Boredom With the Same Food
Some dogs seem less interested in the same food over time.
But don’t try to fix boredom by constantly changing food. That can cause an upset stomach and create picky behavior.
Simple Fix: You can add dog food toppers to your dog’s food or even add something fun to the mealtime, like a lick mat. Henry loves eating from his mats. But if this doesn’t solve the boredom, then talk to your vet about changing dog food.
These are the lick mats Henry enjoys at every meal.
6. Feeding Environment Issues
Sometimes the problem isn’t the food at all.
It’s the location of the bowl.
Evaluate if your dog is eating in a busy or noisy spot.
Although some dogs simply like company. Henry likes me to be nearby while he eats. If I move, he’ll stop eating.
Simple Fix: Evaluate where your dog eats. If it’s in a noisy or busy location, place the bowl in a quieter spot. Or if you discover your dog likes company, place the bowl next to your chair or wherever you will be for a bit. If this doesn’t help, then talk with your vet or call a dog behaviorist.
7. Upset Stomach
Sometimes, if your dog has an upset stomach, he may leave food in his bowl or not want to eat.
Digestive sensitivity can absolutely impact appetite.
I know I don’t like eating when I have a stomachache. Your dog is the same way.
When Henry has a tummy ache, he always leaves some food in his bowl.
Simple Fix: If you suspect your dog has a stomachache, is eating grass, or has a tight abdomen, then wait for the next feeding and see if your dog is more interested. But if your dog still doesn’t want to eat or has other symptoms, call your vet.
8. Dental Pain or Discomfort
If your dog doesn’t want to eat at all or only a bit, there could be a dental or mouth issue. A sign you may have a mouth issue is if your dog refuses his favorite cookie.
Just as it hurts to eat when you have a toothache, the same is true for your dog.
Best Fix: Call your vet if you suspect a tooth or dental issue.
9. Underlying Health Issues
There can be times when your dog has a medical issue and doesn’t feel like eating.
Stay calm, though, until you know what is going on with your dog. Your dog can pick up on your emotions.
Best Fix: It’s always best to catch a medical issue early, so when in doubt, call your vet to rule out or in any health issue. Then you can address any health problem appropriately.
