All kinds of raisin products such as raisin paste, raisin juice, and water are toxic to cats and dogs. Dogs should never eat grapes, raisins, or currants since they are poisonous and may cause renal failure. When raisins are consumed in combination with other foods, the potential for contamination may be larger than when grapes or currants are consumed. There is still concern over the level of toxicity. Determine which types of grapes and raisins may be harmful to dogs and find out how to avoid feeding them. Grapes, whether professionally manufactured or handmade, red or green grapes, raisins, and organic or non-organic grapes have all been known to poison canines when consumed in sufficient quantities. Products such as raisin bran cereal, trail mix, granola mix, and baked goods that include grapes, raisins, or currants could contain harmful toxins. It would seem that grape jellies and grape juice do not provide a toxicity risk to consumers. The use of any of these fruits in quantities that are known to cause harm is not recommended at this time; nevertheless, two broad recommendations may be observed. Canine sensitivities seem to be "specific," the danger of a dog being poisoned rises when the dog consumes a large amount of fruit.
Some dogs won't be harmed by eating a handful of grapes or raisins, but others might get ill after eating even a very little quantity of the fruit. Grapes and raisins both contain a substance that could make dogs sick. To the best of our knowledge, there is no method available that can be used to identify which dogs will be at the most risk. At this point, we do not know what it is about these fruits that causes them to be toxic. Over the years, there has been a great deal of speculation on whether or not the grape's toxicity is the result of a naturally occurring mycotoxin (a poisonous substance that is produced by fungus or mold) or a salicylate medicine (a drug that is similar to aspirin). Recent hypotheses have concentrated on tartaric acid as a likely offender in this case. However, there has not been identified a single potentially harmful chemical as of yet. Because it is not known what about these fruits causes them to be toxic, coming into contact with them might put one in danger. If you believe that your pet may have eaten any of the fruits described above, you should immediately make contact with your veterinarian, the Pet Poison Helpline, or an animal poison control group. Due to the fact that there are still many doubts about this poisoning, it is in your best interest to avoid taking any risks to your dog's health. If you catch the poisoning in its early stages and provide treatment, not only will your pet be safer, but you'll also end up saving money.
raisin toxic to dogs
For dogs and cats, it is not a good choice to feed them with the raisin and the product which include it, but it is not toxic to other animals such as birds. If you and your dog both like the somewhat sour, slightly sweet, and fruity flavor of raisins, you may have thought of sharing some of those delightful morsels. Regrettably, the answer to that question is no. Canines are very susceptible to the toxicity of raisins and the grapes used to make them. Due to their high toxicity, grapes and raisins may cause a rapid and perhaps deadly loss in renal function in dogs. The next section will lead you through what to do if your dog consumes one of these treats. Poisoning from grapes and raisins usually manifests itself within twenty-four hours, with vomiting being the most visible and dramatic early sign. You may also notice that you have lost your appetite, are feeling quite exhausted, and have diarrhea in the 12 to 24 hours that follow. Most severe symptoms do not manifest until 24 to 48 hours after intake, which is a substantial length of time after the acute renal injury has already started to take effect. Nausea, vomiting, loss of appetite, shortness of breath (uremic, or ammonia odor), diarrhea, abdominal discomfort, intense thirst, and frequent urination are all signs of acute kidney failure. 
The same symptoms may be caused by chronic renal illness. It is likely that the dog may eventually cease peeing due to renal failure caused by the toxin. It is not unusual for the dog's blood pressure to soar to dangerously high levels after this. The dog may go into a coma as a consequence of the accumulation of chemicals that the kidneys would normally remove via urine. The prognosis deteriorates dramatically after the loss of renal function and the end of urine output. Because the early symptoms of grape or raisins poisoning are non-specific, they might be ready for mistaken those of other disorders, such as a simple dietary error (eating foods that should not be eaten). More advanced symptoms are similar to those found in other types of renal failure. Your dog's history of grape or raisin consumption will aid your veterinarian in making a diagnosis of grape or raisin poisoning. Alternatively, the presence of grape or raisin bits in the dog's vomit may be used to make the diagnosis. In order to establish the extent of renal impairment in your pet, your veterinarian may prescribe a complete blood count (CBC), urine, and other diagnostic procedures. The findings of the tests will be crucial in deciding the dog's prognosis. The aim of therapy is on preventing or limiting toxin absorption in order to maintain or reduce renal function. The recommended course of action is to induce the dog's vomiting reflex as soon as possible and offer activated charcoal to decontaminate it as soon as possible. As a result, the poison is less likely to be absorbed by the body via the digestive system. Because of the length of time grapes and raisins may linger in the stomach, it is critical that the individual be compelled to vomit (even up to 4-6 hours after ingestion). 
Following decontamination, the patient may need further therapy, such as intensive IV fluids, to maintain and protect the kidneys in the hopes of limiting the damage done to them. There is also the option of administering medication to the patient in order to avoid or cure nausea and vomiting, maintain blood flow to the kidneys, and keep blood pressure at a healthy level.
