Most people are aware that HUMAN chocolate should not be fed to their dog, but unfortunately the list of things to avoid is a lot longer than one item.  Onion and garlic should also be on the list cooked or raw and homeopathic followers will add that any food from the deadly nightshade family should be avoided at all costs and I have listed some in the section concerning diet.

Along with food stuffs there is also a long list of plants that can have serious and fatal effects on our canine friends and of course there is also the list of medication and chemicals both in the home and in the garden shed, the most common one being snail bait.  What people don't realise though is that even if the dog is kept away from the actual substance, it only has to have residue on shoes, gloves or clothing that the dog then gets to and licks or chews for poisoning to occur. 

Dog (and cat) owners should consider provention of their animal coming into contact with chemicalsand the storage of the chemicals in the same manner as they would for preventing children from coming into contact with them.  They say an ounce of prevention is worth a pound of cure.

Unfortunately, we lost a dog many years ago to snail bait.  Not from any we owned but from some kind person throwing a packet in to our back yard while we were out.  But no matter how the poisoning happens, it is always very distressing for both owner and animal.  Our Brandy didn't ask to be poisoned but she paid the ultimate price.  Training your dog to only eat when you give permission can sometimes be life saving.   Brandy was too young.  So dilegence is our best protection.

If you mulch your garden to be water wise, then do be aware that cocoa mulch is toxic, it contains an ingredient that smells like chocolate and is very attractive to them called Theobromine.

Now for a list of household items.

Beverages with caffeine (like soda, tea, coffee) acts as a stimulant and can accelerate your pet's heartbeat to a dangerous level. Pets ingesting caffeine have been known to have seizures, some fatal.

Chewing Gum or Sugarfree Lollies
Sugarfree gum or lollies containing xylitol has been recognised to be a risk to pets. This compound can cause seizures, liver damage and death in some dogs. This information is recent and some vets may not be familiar with xylitol poisoning.

The seed pit contains cyanogenic glycosides which can cause cyanide poisoning.

Chocolate contains theobromine, a compound that is a cardiac stimulant and a diuretic. When affected by an overdose of chocolate, a dog can become excited and hyperactive. Due to the diuretic effect, it may pass large volumes of urine and it will be unusually thirsty. Vomiting and diarrhea are also common. The effect of theobromine on the heart is the most dangerous effect. Theobromine will either increase the dog’s heart rate or may cause the heart to beat irregularly. Death is quite possible, especially with exercise. Symptoms of chocolate poisoning include: vomiting, diarrhea, tremors, hyperactivity, irregular heartbeat and seizures.

After their dog has eaten a large quantity of chocolate, many pet owners assume their pet is unaffected. However, the signs of sickness may not be seen for several hours, with death following within twenty-four hours.

Citrus Oils
Citrus oil extracts can cause a toxic reaction with vomiting.

Cocoa powder and cooking chocolate are the most toxic forms. These forms of chocolate contain ten times more theobromine than milk chocolate. Even licking a substantial part of the chocolate icing from a cake can make a dog sick. The next most dangerous forms are semi-sweet chocolate and dark chocolate, with milk chocolate being the least dangerous. A dog needs to eat more than a 250gm block of milk chocolate, however the high amount of fat found in milk chocolate can lead to an attack of pancreatitis.

Corn Cobs
Many dogs have suffered and, in some cases, died after eating corn-on-the-cob, because the corn cob caused a partial or complete intestinal obstruction or blockage of the Bowel. Never allow your dog access to corn cobs.

Dairy Products -( Milk )
Most dairy products are not digested well by dogs who have little or none of the enzyme required to digest the lactose in milk. Lactose-intolerant dogs can develop excessive intestinal gas and may have foul-smelling diarrhoea. Small amounts of cheese or plain yoghurt are tolerated by most dogs, as these products have less lactose than most others.

Grapes or Raisins
Although the minimum lethal dosage is not known, grapes and raisins can be toxic to dogs when ingested in large quantities. The symptoms are gastrointestinal signs including vomiting and diarrhea, and then signs of kidney failure with an onset of severe kidney signs starting about 24 hours after ingestion.

Due to the severity of the signs and the potential for death, the veterinarians at the National Animal Poison Control Center (NAPCC) advocate aggressive treatment for any dog believed to have ingested excessive amounts of grapes or raisins, including inducing vomiting, stomach pumping and administration of activated charcoal, followed by intravenous fluid therapy for at least 48 hours or as indicated based on the results of blood tests for kidney damage.

Small amounts of liver are generally well tolerated by most dogs but if the liver intake is too high it can cause nutritional problems due to the high content of vitamin A. Consumption of this vitamin in large amounts can lead to vitamin A toxicity, or hypervitaminosis A. If your dog eats raw liver or consumes three servings of cooked liver a week it could lead to bone problems. Symptoms of hypervitaminosis A are deformed bones, excessive bone growth on the elbows and spine, weight loss and anorexia. If left unchecked, hypervitaminosis A has in some cases caused death.

Macadamia Nuts
The toxic compound is unknown but eating as few as six nuts without the shell has been known to cause elevated body temperature, accelerated heartbeat, tremors in the skeletal muscles, and weakness or paralysis of the hindquarters. Affected dogs have difficulty or are unable to rise, are distressed and usually panting.Some affected dogs have had swollen limbs and showed pain when the limb was manipulated. Dogs did recover from the muscle weakness and pain and it is not known if there have been any fatal cases. Macadamia butter is included in this warning.

Mouldy or Spoiled Foods
The common mold found growing on many foods contain toxins such as Penicillium mold toxins or tremorgenic mycotoxins. Symptoms of poisoning include severe tremors and seizures that can last for hours or even days. This is considered an emergency and medical treatment is needed to control the seizures and detoxify the dog.

Nutmeg is reported to be a hallucinogenic when ingested in large doses. Nutmeg has been known to cause tremors, seizures and in some cases, death.

Nuts in general are not good for dogs as their high phosphorus content may lead to bladder stones.

Do not give your dog sips of any alcoholic beverage. Ingestion can lead to injury, disorientation, sickness, urination problems or even coma or death from alcohol poisoning. Some dogs are attracted to alcoholic drinks so be careful not to leave one lying around where a dog can reach it.

Apple &Apricot
The seeds contain cyanogenic glycosides which can lead to cyanide poisoning. 

Avocado contains a toxic element called persin which can damage heart, lung and other tissue in many animals. Avocadoes are high in fat content and can trigger an upset stomach, vomiting or even pancreatitis. The seed pit is also toxic and if swallowed can become lodged in the intestinal tract where it may cause a severe blockage which will have to be removed surgically.

Peaches, Pears, Plums
The seed pits contains cyanogenic glycosides which can cause cyanide poisoning 

Also consider the risk of chocking or bowel blockage from the swallowing of the large stones inside some fruits.

The RSPCA Australia has a web site worth visiting  for more information.

At the end of the day, if you think that your dog has ingested something it shouldn't have, get it to a vet
