Is it true that chocolate could kill my Dane?
Chocolate contains theobromine that is toxic to dogs in sufficient quantities. This is a xanthine compound in the same family of caffeine, and theophylline.
Toxic Levels:
Based on a ratio between the amount of theobromine - relative to the the dog's weight, it takes, on average about 100-150 mg/kg of theobromine to cause a toxic reaction.
The individual sensitivity, dog's age, size and chocolate concentration are variables to consider
On average,
Milk chocolate contains 44 mg of theobromine per oz.
Semisweet chocolate contains 150mg/oz.
Baker's chocolate 390mg/oz.
Using a dose of 100 mg/kg as the toxic dose it comes out roughly as:
1 ounce per 1 pound of body weight for Milk chocolate
1 ounce per 3 pounds of body weight for Semisweet chocolate
1 ounce per 9 pounds of body weight for Baker's chocolate.
So, for example, 2 oz. of Baker's chocolate can cause great risk to an 15 lb. dog. Yet, not as dangerous for a 170 lb Great Dane. However, a 6 weeks Great pup, which would be
about 15 lb in weight, would be in a higher risk by a 2 oz Baker's chocolate than a 6 years old - 15 lb toy dog exposed to the same quantity of chocolate.
Clinical Signs
Xanthines affect the nervous system, cardiovascular system and peripheral nerves. It has a diuretic effect as well.
Clinical signs:
Hyper excitability
Hyper irritability
Increased heart rate
Restlessness
Increased urination
Muscle tremors
Vomiting
Diarrhea
Treatment
There is no specific antidote for this poisoning. And the half life of the toxin is 17.5 hours in dogs. Induce vomiting in the first 1-2 hours if the quantity is unknown. Administering activated charcoal may inhibit absorption of the toxin. An anticonvulsant might be indicated if neurological signs are present and needs to be controlled. Oxygen therapy, intravenous medications, and fluids might be needed to protect the heart.
Milk chocolate will often cause diarrhea 12-24 hours after ingestion. This should be treated symptomatically (fluids, etc..) to prevent dehydration.
If you suspect your pet has ingested chocolate contact your Vet immediately! They can help you determine the proper treatment for your pet.
I received this question several times. It seems that several browsers did not go through the library section carefully.
Yes. Please go to the library page and examine the three pages addressing this topic.
In fact, I can decide or select the time the female would go in estrus and even control and predict the colour of the puppies. Not just I have done it several times, I offered several consultations to breeders with full success.
