Yesterday, I gave my dog a Greenie after his usual dinner, thinking it would help with his oral health. However, about an hour later, he started to vomit. Could the Greenie be the cause, or might something else be upsetting his stomach?
It’s possible that your dog’s vomiting is related to the Greenie, but it’s important to consider other potential causes for the upset stomach as well.
When introducing any new treats or food to your dog’s diet, it’s important to monitor for adverse reactions like vomiting, diarrhea, or changes in behavior. While Greenies are generally considered safe for most dogs, some may have trouble digesting them or might react to an ingredient.
To definitively determine whether the Greenie or another factor is to blame, observe for additional symptoms or repeated incidents. If vomiting persists or is accompanied by other concerning symptoms such as lethargy, diarrhea, or changes in behavior, it’s advisable to consult a veterinarian for a comprehensive assessment.

Ever noticed your furry friend feeling a bit off after munching on those popular green dental treats? You’re not alone! As a dog owner myself, I’ve wondered about this too. Greenies are super popular dental chews that promise fresher breath and cleaner teeth, but can they also cause tummy troubles? Let’s dig into what’s really going on when Greenies meet your dog’s digestive system.
The Truth About Greenies and Digestive Upset
Yes, Greenies can upset some dogs’ stomachs, though this is generally rare and often the result of improper use Most pups handle them just fine, but like people, dogs can have individual sensitivities that might lead to digestive issues.
Here’s what might be happening if your dog has tummy troubles after enjoying a Greenie:
Common Symptoms of Greenie-Related Stomach Upset
If Greenies don’t agree with your dog, you might notice:
- Vomiting – Sometimes happens shortly after consumption
- Diarrhea – Loose stools within 24 hours of eating a Greenie
- Lethargy – Seeming unusually tired or uninterested
- Abdominal discomfort – Whining, pacing, or a hunched posture
- Gas or bloating – Especially after overconsumption
Why Might Greenies Cause Tummy Troubles?
There are several reasons why some dogs experience digestive upset after having Greenies
-
Improper chewing: Dogs who gulp down large pieces without proper chewing can experience digestive issues or even blockages.
-
Ingredient sensitivities: Some dogs may be sensitive to specific ingredients in Greenies, such as:
- Wheat gluten
- Glycerin
- Various proteins
-
Overconsumption Giving too many Greenies can overload the digestive system, leading to upset
-
Size mismatch: Using a Greenie that’s too large or too small for your dog’s size.
Dr. Hannah Lau, a veterinarian who actually uses Greenies for her own pets, notes that while they’re generally safe, the digestive issues are usually related to how they’re given rather than the product itself.
Who Shouldn’t Have Greenies?
Not all dogs should munch on these dental treats. You might want to skip Greenies if your dog:
- Is under 6 months old (puppies have sensitive tummies and developing teeth)
- Has a history of gastrointestinal issues
- Tends to gulp food without chewing
- Has dental problems that make proper chewing difficult
- Has known food allergies to ingredients in Greenies
How to Safely Give Greenies to Your Dog
Want to avoid any potential tummy troubles? Here’s how to serve up Greenies safely:
-
Choose the right size: Select Greenies based on your dog’s weight, not just breed.
-
Supervise chew time: Always watch your dog while they’re enjoying a Greenie to ensure they’re chewing properly.
-
Limit consumption: Stick to the recommended guidelines – generally one Greenie per day at most.
-
Introduce slowly: If your dog is new to Greenies, start with a small piece to check for any adverse reactions.
-
Ensure proper chewing: If your dog tends to gulp treats, try breaking the Greenie into smaller pieces.
I remember when I first gave my Lab mix a Greenie – he tried to swallow it whole! Now I break them up and make sure he actually chews before swallowing. Makes a big difference!
What the Experts Say: Vets’ Opinions on Greenies
Greenies have received mixed reviews from veterinary professionals. While many vets do recommend them as part of a dental care routine, others express concerns about potential digestive issues.
The Veterinary Oral Health Council (VOHC) has given Greenies their seal of approval for reducing tartar and plaque. However, this doesn’t necessarily mean they’re perfect for every dog’s digestive system.
According to information from Fluffy Tamer, some vets have encountered cases where dogs experienced adverse reactions to Greenies, including vomiting, diarrhea, and intestinal issues. There have also been concerns about additives that might encourage dogs to swallow them too quickly.
What About That Recall?
It’s worth noting that Greenies underwent a reformulation after some safety concerns. In February 2023, the FDA announced a recall of certain Greenies dog treats due to potential mold contamination. The FDA also issued a warning after receiving reports of dogs experiencing gastrointestinal issues after consuming Greenies.
The good news? The company has since improved the digestibility of Greenies, making them safer for most dogs. The new formula dissolves more easily, reducing the risk of blockages that plagued earlier versions.
Alternative Options If Greenies Don’t Work for Your Dog
If your dog consistently has stomach issues after eating Greenies, don’t worry! There are plenty of alternatives:
- Whimzees Dental Chews: Plant-based and hypoallergenic with simple ingredients
- Virbac C.E.T. VeggieDent Chews: Made with limited ingredients and free of animal proteins
- Zuke’s Z-Bone Dental Chews: Grain-free, potato-based chews for sensitive dogs
- Himalayan Yak Chews: Natural alternative with fewer ingredients
- Beef Pizzle (Bullysticks): Single-ingredient option for sensitive tummies
- Raw carrots or apples: Natural, low-calorie alternatives (always supervise!)
The Bottom Line: Risk vs. Reward
Let’s be real – no treat is perfect for every dog. Here’s my take on Greenies:
Pros:
- Effectively reduce plaque and tartar
- Help freshen breath
- Most dogs love the taste
- Approved by the Veterinary Oral Health Council
- Come in different sizes for all dogs
Cons:
- Can cause digestive upset in sensitive dogs
- Potential for blockages if not chewed properly
- Not suitable for puppies under 6 months
- High in calories and carbohydrates
- May cause allergic reactions in some dogs
Frequently Asked Questions
How long does it take for a dog to digest a Greenie?
Most dogs digest a properly chewed Greenie within 12-24 hours. If your dog swallowed large pieces, it might take longer. The reformulated Greenies are designed to break down more easily in the digestive tract.
Can one Greenie make my dog sick?
Yes, even one Greenie can potentially cause stomach upset if your dog has a sensitivity to an ingredient or if they don’t chew it properly before swallowing. Individual reactions vary widely.
Why does my dog vomit after eating Greenies?
Vomiting after eating Greenies may indicate that your dog:
- Has a sensitivity to an ingredient
- Swallowed pieces that were too large
- Ate too quickly
- Consumed too many at once
Are there any warning signs of a serious problem?
Watch for these red flags that might indicate something more serious than simple stomach upset:
- Repeated vomiting
- Inability to keep water down
- Blood in vomit or stool
- Severe lethargy
- Abdominal swelling or pain
- No bowel movements for 24+ hours
If you notice any of these symptoms, contact your veterinarian immediately as they could indicate a blockage or other serious condition.
My Final Thoughts
As a dog owner who’s used Greenies (and dealt with the occasional tummy upset), I think they can be a valuable part of your dog’s dental care routine – if used properly. The key is knowing your individual dog’s sensitivities and making sure they chew thoroughly.
Remember, dental treats should complement regular tooth brushing, not replace it. And when in doubt about your dog’s reaction to any treat, your vet is always the best resource!
