11 OF THE MOST DANGEROUS FOODS YOU SHOULD NOT GIVE YOUR DOG.

1. Alcohol
   
   Most ingredients use in alcoholic beverages eg. Grapes, hops etc. are toxic to dogs and what makes them toxic is mostly still a mistery to veterinary science. When a consumes alcohol the dog will experience not only these physical symptoms such as vomiting, wild fluctuations in body temperature, and labored breathing, but also potential kidney damage. So enjoy your drinks responsibly, and without your dog.
   2.Avocados
   
   There are still debates on whether or not if avocados are dangerous to dogs. Some say the seed or pit can choke and suffocate a dog to death others say the pit contains persin which is toxic to dogs, but what matters the most is that most dogs fall sick when they consume avocados. So then why give you cute little pup an avocado why not try peanut butter instead.
   3.Chocolate
   
   Chocolate is poisonous to dogs; however, the hazard of chocolate to your dog depends on the type of chocolate, the amount consumed and your dog's size. In large enough amounts, chocolate and cocoa products can kill your dog.The toxic component of chocolate is theobromine. Humans easily metabolize theobromine, but dogs process it much more slowly, allowing it to build up to toxic levels in their system.A large dog can consume more chocolate than a small dog before suffering ill effects.A small amount of chocolate will probably only give your dog an upset stomach with vomiting or diarrhea.With large amounts, theobromine can produce muscle tremors, seizures, an irregular heartbeat, internal bleeding or a heart attack. The onset of theobromine poisoning is usually marked by severe hyperactivity.
   The usual treatment for theobromine poisoning is to induce vomiting within two hours of ingestion. So never use chocolate as treat

4.Grapes and Raisins

A single serving of raisins or grapes can cause serious illness or death in some dogs. Because the toxin accumulates internally, even a dog who has no negative reaction to these fruits may become extremely ill over time. Early symptoms of grape or raisin poisoning include vomiting and diarrhea, followed by lethargy, dehydration, lack of appetite, decreased urination and kidney failure that can result in chronic kidney disease or death.

5.Onions and Garlic

Onions, garlic, scallions and shallots contain disulfide, a compound that can damage dogs’ red blood cells. When dogs eat raw onions or garlic, they risk developing hemolytic anemia, which occurs when destroyed red blood cells cannot be replaced. Eating powdered forms of onion or garlic in soups, dips or sauces is also toxic. Signs of internal damage, such as weakness, orange-colored urine, tiring easily or resisting movement, may not appear for a few days. If you notice these symptoms, immediately take your dog to a veterinarian or emergency clinic where a blood transfusion may be necessary.

6.Baking Dough

Uncooked bread dough that contains yeast can be dangerous for any dog who ingests it. The stomach's moist warmth provides a perfect environment for the yeast in raw dough to rise, which can cause intense discomfort and lead to the dog's stomach or bowel to rupture. The expanding stomach can press against the dog's diaphragm, making breathing difficult. If your dog has eaten bread dough, she needs to be examined by a veterinarian immediately.

7.Nuts

Nuts are unhealthy for dogs because their high phosphorus content may lead to bladder stones. Walnuts are poisonous for dogs, as are macadamia nuts. Eating even a few macadamia nuts can be harmful, leading to vomiting, muscle pain, joint swelling and overall weakness. Dogs who have eaten macadamias may experience hypothermia, dizziness, coordination problems, tremors and a high fever. Consult your veterinarian immediately if your dog exhibits any of these symptoms.

8.Fatty Foods

Dogs are fond of meat and other high-fat foods, but cooked and uncooked meat table scraps and fat trimmed from meat can cause pancreatitis. Unfortunately, some people treat dogs with leftovers, and dogs sometimes treat themselves by stealing food. Pancreatitis in dogs often follows the consumption of a fatty meal or snack. Your dog may become very sick quickly, and if you notice symptoms such as sudden vomiting, diarrhea and abdominal pain, she should be examined by a veterinarian and receive intensive fluid and antibiotic therapy.

9.Nutmeg

The same nutmeg used in baking or sprinkled on eggnog can be very toxic to dogs, and the oil in nutmeg may cause central nervous system damage. Nutmeg toxicity can result in abdominal pain, vomiting, muscle spasms, irregular heart rate, dizziness, tremors, extreme sleepiness, personality changes, seizures and hallucinations. Your dog needs to be examined by a veterinarian immediately, because if treated too late or left untreated, nutmeg poisoning may be fatal.

10.Xylitol

Xylitol is a sweetening agent used in sugar-free gum and candy, and as a sweetener added to sugar-free baked goods. Products containing xylitol should never be given to or within reach of dogs. Symptoms of xylitol poisoning include vomiting, lethargy, loss of coordination, erratic behavior, disorientation and seizures. Eating candy, gum or baked foods made with xylitol can cause a severe drop in blood-sugar levels, resulting in liver failure. If you suspect your dog has ingested xylitol, she should be taken to a veterinarian or an emergency clinic immediately.

11.Rawhide Treats

Feeding rawhide treats can bring about a range of problems. Some rawhide products have tested positive for toxic chemicals or for salmonella and E. coli bacterial contamination. If you give your dog rawhide, supervise her while she is chewing it, because it softens and becomes enlarged by dog saliva. Rawhide must be taken away prior to being swallowed, because it continues to expand in the stomach or intestines, causing a blockage that may require emergency surgery. Contact your veterinarian immediately if your dog’s symptoms include gagging, repetitive swallowing, vomiting, diarrhea, signs of pain, lack of energy, loss of appetite or a fever.
