1. Chocolate
Chocolate contains theobromine, a substance toxic to dogs and can lead to serious health problems, even death. The amount of theobromine varies depending on the type of chocolate, with dark chocolate and unsweetened baking chocolate having the highest concentrations. Just a small amount of ANY chocolates, including white chocolate, can cause symptoms such as vomiting, diarrhea, increased thirst, hyperactivity, seizures, muscle tremors, and even death. To keep our dogs safe, it’s important to keep all chocolate and chocolate-containing items well out of their reach. But, if the worst happens, and your dog ingests chocolate, don’t panic, seek veterinary treatment immediately. Treatment for chocolate toxicity may include: inducing vomiting, administering activated charcoal, providing IV fluids, heart medications, anti-convulsants, and antacids. With proper, prompt treatment, most dogs will fully recover.

2. Grapes and Raisins
Ingesting grapes and raisins can lead to kidney failure in dogs and can be life-threatening if not treated promptly. The exact toxic substance in grapes and raisins is still unknown, and it’s also unclear why some dogs can eat them without any problems while others are severely affected. Symptoms of grape or raisin toxicity include vomiting, diarrhea, lethargy, decreased appetite, and increased thirst. If you suspect your dog has ingested grapes or raisins, it’s crucial to seek veterinary treatment immediately. Treatment may include inducing vomiting, administration of activated charcoal, IV fluid therapy, and monitoring of kidney function. So, while grapes and raisins may be a healthy snack for us, it’s best to keep them away from your pup and ensure their safety.
The amount of grapes or raisins that can be toxic to dogs varies depending on the size, breed, and age of the dog. Even small amounts of grapes or raisins, such as a handful or a single grape or raisin, can be toxic to dogs and lead to kidney failure.

3. Onions and Garlic
Both onions and garlic contain compounds that can damage a dog’s red blood cells, leading to anemia, which can be life-threatening if left untreated. Symptoms of onion and garlic poisoning can include vomiting, diarrhea, abdominal pain, breathlessness, and a yellowish tinge to the eyes and gums. Ingesting even small amounts of these foods can be toxic to dogs, with the toxicity increasing with the amount consumed. As little as 5 grams of onions per kilogram of a dog’s body weight can cause damage to their red blood cells. This includes onion powder and/or onion flakes as well as leeks and chives.
If you suspect your dog has ingested onions or garlic, it’s important to seek veterinary treatment immediately. Treatment may include blood transfusions, IV fluid therapy, and monitoring of the dog’s blood values.

4. Alcohol
Ingesting even small doses of alcoholic drinks can cause serious health problems in dogs, including vomiting, low body temperature, diarrhea, lack of coordination, breathing difficulties, and even coma or death. The toxic effects of alcohol poisoning depend on the type, amount, and size of the dog, but it’s important to keep in mind that dogs are much more sensitive to the effects of alcoholic drinks than humans are.
If you suspect your dog has ingested any alcoholic beverages, it’s important to seek veterinary treatment immediately. Treatment may include induction of vomiting, administration of activated charcoal, IV fluids to prevent dehydration, and close monitoring of the dog’s vital signs.

5. Macadamia Nuts
Toxicity in macadamia nuts for dogs is a result of an unknown compound that affects their central nervous system. While the exact cause is still uncertain, it is believed that dogs are unable to metabolize this compound properly, leading to adverse reactions. Symptoms of macadamia nut toxicity in dogs include weakness, tremors, vomiting, and increased body temperature. In severe cases, dogs may experience difficulty walking or even paralysis. Ingesting as little as 0.3 ounces of macadamia nuts per kilogram of a dog’s body weight can cause these symptoms.
If you suspect your dog has ingested macadamia nuts, it’s important to seek veterinary treatment immediately. Treatment may include inducing vomiting, administration of activated charcoal, and monitoring of the dog’s body temperature, as well as providing supportive care such as IV fluids.

6. Avocados
Avocados contain persin, a fungicidal toxin that can cause vomiting, diarrhea, and even fluid buildup in the chest and abdomen in dogs. The severity of symptoms depends on the amount of persin ingested and the size of the dog, but even a small amount can be toxic.
If you suspect your dog has ingested avocados, it’s important to seek veterinary treatment immediately. Treatment may include inducing vomiting, administration of activated charcoal, and providing supportive care such as IV fluids.

7. Xylitol
Xylitol is a sugar substitute that is commonly used in many sugar-free products. It is sometimes found in peanut butter, which dog owners have long since used as a special treat for their pups. While believed safe for human consumption, in moderation, xylitol can be extremely dangerous for dogs if ingested. When dogs eat xylitol, it can cause a rapid release of insulin in their bodies, leading to a sudden decrease in blood sugar levels. This condition, known as hypoglycemia, can result in symptoms such as vomiting, loss of coordination, seizures, and even liver failure. It is important for dog owners to be aware of the potential dangers of xylitol and to keep any products containing this artificial sweetener out of reach of their dogs. Xylitol ingestion is a serious concern, and prompt veterinary care is necessary.
