Has your dog eaten too many Greenies? Are you worried the Greenies will make him sick? If so, then you’ve come to the right place.
In this article, we’ll take a look at what Greenies are and whether or not they can make your dog sick. Let’s get started!
What are Greenies?
Greenies are a dog dental chew, which is supposed to help keep dogs’ teeth healthy and improve bad breath. The treats are a green color and look a little bit like a toothbrush on one end. Greenies are supposed to remove plaque and tartar and keep a dog’s teeth cleaner.
Greenies have been popular for years; however, there have been some cases where dogs swallowed one or more Greenies and developed a blockage. In some cases, the dogs died.
These treats are made of natural ingredients, which include:
- Wheat flour
- Glycerin
- Wheat gluten
- Gelatin
- Water
- Powdered cellulose
- Lecithin
- Minerals
- Turmeric color
These treats are nutritionally complete and are made with easily digestible ingredients. However, can Greenies make your dog sick? What happens if your dog has too many Greenies?
Greenies & Dogs
Too many Greenies can make your dog sick. Dogs may develop digestive issues, or if large pieces of the Greenies were swallowed, they could lead to an intestinal blockage. This is a painful condition that can lead to death if not treated urgently by your vet.

You may notice these symptoms if your dog has eaten too many Greenies:
- Nausea
- Vomiting
- Empty retching
- Abdominal pain & swelling
- Excessive panting
- Lethargy
- Reduced appetite
- Diarrhea
- Constipation/lack of feces
If you notice any of these symptoms in your dog, it’s time to call the vet. This could be a medical emergency.
One note: Do not induce vomiting. If the vet recommends this, they will induce vomiting in the veterinary clinic.
If possible, try to figure out how many Greenies your dog has eaten and try to determine if they chewed them up or ate them in large chunks. It can also help to bring the packaging along when you visit the vet.
Treatment of an Intestinal Blockage in Dogs
At the vet’s, they will first perform a complete physical exam on your dog. They may then decide to further investigate your dog’s illness. This may include lab work, x-rays and an ultrasound. The x-rays and ultrasound will help the vet see if there’s a blockage and where it’s located in the dog’s digestive tract.
If the images show a blockage, then your canine companion will need emergency abdominal surgery to safely remove it. Your vet will discuss this in detail with you if your dog needs surgery.
The good news is that in most cases, dogs who receive prompt medical treatment will go on to make a full recovery. Your fur baby will be back to normal in a couple of weeks!
