What is Bone Meal and Blood Meal Fertilizers Poisoning?
Having a beautiful garden during growing season is a hobby that many pet owners enjoy. Being aware of the hazards that natural substance meals and other fertilizers can present is an important part of pet ownership. Dogs and cats are curious creatures by nature, and in addition to this trait, canines find bone meal and blood meal to be very palatable. Bone meal is made from ground up animal bones while blood meal is flash-frozen blood that is ground up as well, both intended to be easily mixed with soil in the garden. Bone meal and blood meal poisoning can occur when your pet eats a large amount of the product by breaking into a bag stored within their reach. The main dangers from bone meal are intestinal obstruction and pancreatitis, while blood meal can often contain iron which can prove to be toxic in large doses.
Bone meal and blood meal are considered organic fertilizers, used in the garden as a supplement to enhance the growth of plants. Incidents of ingestion of these fertilizers in large amounts directly from the bag are common due to the palatability of the fertilizers to dogs.

Symptoms of Bone Meal and Blood Meal Fertilizers Poisoning in Dogs
The severity of symptoms of ingesting either of these two fertilizers will depend on how much was eaten. A small ingestion could cause mild gastrointestinal upset. A significant exposure and intake could mean that your pet will become very ill.
- Vomiting (including bloody vomit)
- Diarrhea (sometimes very foul smelling due to the presence of blood in the fertilizer)
- Bloating and pain in abdomen
If there is an iron toxicity from a large ingestion of blood meal you may see muscle tremors and blood in the stool in addition to the above signs of poisoning. In some cases, bone meal and blood meal that has been in an opened bag for some time can develop mold. This can cause mold poisoning; your pet may suffer from seizures or tremors. Both bone meal and blood meal can cause pancreatitis (especially if your dog is predisposed), symptoms may include shock, difficulty breathing, and fever, among other serious effects.
Causes of Bone Meal and Blood Meal Fertilizers Poisoning in Dogs
- Dogs may ingest large quantities of blood and bone meal straight from a bag
- They can also dig in the garden because they smell the additives and then ingest other fertilizers that you have mixed in as you garden
- Fish and feather meals may be added to the mixture, increasing the attractive odor for pets
- Bone meal can form into a cement-like ball in your dog’s stomach, requiring surgery for removal
- Gardeners often mix blood and bone meal with fertilizers for their rose bushes; disulfoton is an ingredient in rose bush fertilizer which is extremely toxic
- Moldy fertilizers and meals can cause illness due to mold poisoning and bacteria
- Gardeners sometimes mix bone or blood meal in the soil as they plant bulbs and many bulbs are poisonous to dogs
Diagnosis of Bone Meal and Blood Meal Fertilizers Poisoning in Dogs
If you see that your dog has eaten a large amount of bone meal or blood meal, take him to the veterinary clinic without delay. You may see that he has the evidence in the form of the meal powder on his face and fur. Even if your pet is not showing signs of illness, a veterinary visit is recommended to verify if your dog is free of possible related complications.
As the veterinarian does a physical examination (heart rate, respiratory rate, temperature, abdominal palpation), he may ask the following questions.
- How long ago did your pet ingest the bone or blood meal fertilizer?
- What are the symptoms that prompted you to bring him here?
- How did he gain access to the product (digging in the garden or from a bag) and do you have the packaging with you?
- Is your dog presently on medication and if so, what for?
- Was the bone or blood meal opened some time ago or just recently?
The history that you are able to provide along with physical signs will help the veterinarian make a decision as to the course of action. The veterinary team may do a urinalysis and take blood samples (complete blood count and serum chemistry) to check for pancreatitis and iron toxicity. An abdominal x-ray may show if an obstruction is forming due to the bone meal hardening within the gastrointestinal tract or stomach, and can also point to irritation or enlargement of the pancreas. If the pancreas shows signs of a problem and further imaging is needed, then your veterinarian may order an ultrasound.
Treatment of Bone Meal and Blood Meal Fertilizers Poisoning in Dogs
The treatment for bone meal and blood meal fertilizers poisoning will depend on how well your pet is handling the effects of the toxicity, and ultimately, how much was consumed. As is the case in many poisonings, treatment is done according to what symptoms are present. With a poisoning event by blood meal and bone meal a big concern will be pancreatitis. This can develop particularly if your pet has an underlying illness that could predispose your pet to an episode. Pancreatitis can vary between moderate and severe; treatment will be given accordingly. With the ingestion of blood meal, iron toxicity is also watched out for.
Antinausea medication, gastroprotectants, antiemetics (to relieve vomiting if excessive) and fluids for dehydration are in the treatment protocol for excessive iron intake, pancreatitis, and ingestion of bone meal and blood meal. However, in some instances, the veterinary team may induce vomiting and attempt gastric lavage to try and flush out the blood meal. Bone meal is not easily removed from the stomach so if a cement-like ball is forming, surgery to remove it may be the only option.
Recovery of Bone Meal and Blood Meal Fertilizers Poisoning in Dogs
Fortunately, most cases of bone meal and blood meal fertilizers poisoning are not complicated and can be resolved with supportive care. Often the canine patient will experience gastrointestinal problems at most. If your dog was diagnosed with pancreatic issues as a result, there will be additional instructions upon release from the hospital which can include dietary modification and medication. A dog who has had surgery for an obstruction will require rest and be limited in activity until recovery is complete.
Bone Meal and Blood Meal Fertilizers Poisoning Questions and Advice from Veterinary Professionals
Coco got into some organic transplant fertilizer from Al's Garden center here locally. He vomitted what I hope was most of it last night and had some black stool.I havent seen much bowel movement today. The fertilizer does have some bone meal and feather meal. The bag says nowhere on it like most do, to keep away from animals and children. He seems to be ok but I'm worried as I read more what bone meal can do to animals.

My dogs got into natures care organic bone meal I don't know how much they ate. but they have diarea and are now vomiting. It's been about 24 hours. Their poop is very dark but not really bloody and what they like up is just like foamy substance.
From what I can find online there is nothing particular toxic in Natures Care Organic Bone Meal but the ingredients will cause gastrointestinal symptoms like vomiting and diarrhoea; the symptoms will subside over time, for the next few days it would be best to feed both dogs a bland diet of boiled chicken and rice as well as keeping them hydrated. If you have any concerns further concerns you should visit your Veterinarian immediately or call the Pet Poison Helpline. Regards Dr Callum Turner DVM
