Pet parents have the habit of sharing whatever is being eaten with the dog. It has become instinctive for dog owners to toss scraps of food to the pet. All the remaining food on the plates will go directly to Fido's food bowl. Dog owners mean well in giving human foods to the pet however, this act of kindness can have dangerous and unwanted effects on the pet.
While owners have taken to feeding the pet human foods, it would be necessary to know which human foods are toxic to dogs. Onions must not be included in the diet of the dog as this is one of the human foods toxic to dogs. Onions are favorite cooking ingredients. Onions has the substance theosulphate. Onions have toxic effects on dogs given that these animals do not have the enzyme necessary to metabolize this substance .
Spring onions, red, green and yellow as well as other varieties all contain the substance theosulphate. Cooking or any other processes will not destroy the theosulphate thus the pizza pie, the crunchy onion rings, the hamburgers and all other dishes that have onion as an ingredient must not be given to the dog.
The theosulphate in the ingested onion that will not be metabolized by the dog's system will now cause the hemoglobin's oxidation. Carrying oxygen from the lungs to the different tissues of the body is the function of the protein molecules in the red blood cells known as hemoglobin. The oxidation of hemoglobin will result to the formation of bubble-like clumps in the red blood cells. The bubble-like clumps can be easily destroyed. These Heinz bodies will rupture causing the red blood cells to be destroyed prematurely. The normal functioning of the vital organs will be affected if the normal amount of oxygen is not supplied by the red blood cells that were destroyed prematurely.
The toxicity of onions is dose dependent thus dogs that have been eating small amounts of onions will not show symptoms of poisoning until the toxicity builds up. Onion toxicity symptoms are lethargy and breathlessness due to the insufficient supply of oxygen. Vomiting and diarrhea are other symtoms. Dogs are known to have big appetites but onion poisoning will make the dog refuse food. One good thing about this kind of poisoning is that once the dog owner has stopped feeding the dog onions, the symptoms will be gone and the dog's condition will improve.
