What Are Greenies?

Greenies are special dog treats that come in a fun bone shape and green color.

They are made of natural ingredients like wheat flour and gelatin. 

What’s great about these chews is that they contain proteins, vitamins, and minerals that help give your pup healthy teeth and gum.

They are also designed to give your pet’s teeth and gums a good scrubbing to get rid of the yucky buildup that can cause dental issues. 

Plus they come in different yummy flavors that dogs really love.

How Much Greenies Should Be Given to a Dog?

One a day is the way! 

The manufacturer of the popular chews recommends that we treat our furry pals to a single Greenie a day. 

And if you have a small dog, make sure to choose the smaller-sized version. 

For dogs weighing between 5 to 15 pounds, Teenie Greenies are a perfect fit, while Petite Greenies are good for pups weighing 15 to 25 pounds.

What Problems Will There Be If a Dog Ate a Whole Bag of Greenies?

What Problems Will There Be If a Dog Ate a Whole Bag of Greenies

Uh oh!

That would be too many treats for them to handle in one sitting.

For reference, the 27 oz bag of Greenies contains 27 treats, while the 36 oz bag has 36.

Let’s take a closer look at what could happen.


If your pup eats too many Greenies, they might vomit due to an upset stomach. 


Another possible consequence of overeating Greenies is diarrhea.

Your dog’s digestive system might not be able to handle such a large amount of treats at once.


If your dog consumes too many Greenies, they might feel lethargic or tired.

This is because the extra treats can cause their blood sugar to spike and then crash.


If your pet is vomiting and pooping a lot because of overeating, you can expect them to become dehydrated.  

Abdominal pain

Your pup might experience discomfort or pain in its abdominal area and you may also notice their tummies bloating a little.

Reduced appetite

Overeating Greenies can also cause your dog to lose their appetite, as their stomach might be too full or upset to eat.

What to Do if Your Dog Ate Greenies?

What to Do if Your Dog Ate Greenies

What should you do after you find out that your pet scarfed down an entire bag of dental chews?

Here are some suggestions:

Stay calm and assess the situation

Keeping calm is key, so you can carefully assess the situation. Plus, panicking will stress out your already anxious pet.

Deep breaths!

Now, go ahead and find out important information that you will need to relay to your pet’s vet in case your furry pal starts showing adverse reactions.

Limit food and water intake

Your pet is now super full, so it is best to give them just small sips of water in the meantime.

Allow their body to digest the Greenies and let their stomach settle. 

Determine how many Greenies your dog ate

Finding out exactly how many doggy treats your pup ate would help your vet better assess the situation. 

Did they get into an entire fresh bag of treats? Or did they just finish an already-opened bag? 

Knowing this information will help your vet determine the severity of the situation and the best course of action to take. 

Check for any signs of discomfort or distress

Be on the lookout for any signs that your dog is not feeling well. 

Along with the symptoms mentioned earlier such as vomiting, diarrhea, and lethargy, also keep an eye out for restlessness, bloating, empty retching, panting, pacing, or whimpering. 

Contact your veterinarian or a pet poison control hotline

If your dog has eaten too many Greenies and is showing any adverse reaction, don’t hesitate to contact your veterinarian or a pet poison control hotline. 

They will tell you what you need to do next or they may also recommend that you bring your poor furry pal in for a quick checkup.

Do not attempt to induce vomiting unless instructed

Unless your vet or a pet poison control hotline instructs you to do so, resist the urge to make your furry friend vomit. 

Forcing your pet to vomit can be uncomfortable and potentially dangerous, especially if the treats become stuck in the esophagus or airway.

Let the professionals handle it.

How Can I Prevent My Dog From Eating Too Many Greenies in the Future?

Preventing your furry friend from overindulging in Greenies in the future is easier than you might think! 

Store your Greenies in a secure location that your dog cannot get to.

This will help prevent your pup from helping themselves to the entire bag.

Stick with one chew a day and remember to give your pup the right size of Greenies.

The regular variant may be too big for your small pet.

Use Greenies as a treat, not a meal replacement, and always supervise your furry pal while they enjoy their doggy treat.

Frequently Asked Questions (FAQs)

Can Greenies cause blockages in a dog’s digestive system?

Yes, Greenies or any other dental chews can cause blockages in a dog’s digestive system, especially if the dog eats a large number of the chews in one sitting or swallows them whole without properly chewing them. 

Can eating too many dental chews have different effects depending on the type of chew?

Yes, different types of dental chews have different ingredients and nutritional values. Some may contain higher levels of certain nutrients, such as sugar, leading to potential health issues if consumed in excess. 

Do dental chews make dogs sick?

Eating dental chews can sometimes cause dogs to experience vomiting, diarrhea, or lethargy, especially if they consume them in excessive amounts or swallow them whole. It’s best to introduce dental chews gradually and monitor your dog’s reaction.

Can Greenies cause allergic reactions in dogs?

Yes, some dogs may be allergic to certain ingredients in Greenies, such as wheat. Signs of an allergic reaction may include itching, hives, or difficulty breathing. If your dog experiences any of these symptoms, stop giving them the dental chews and consult with your vet.
