Dog Food

Before giving your dog food you should stop to do research on how it would affect him. To keep your dog healthy you will need to know that the dog food you are feeding to your dog is safe.

 Not All Human Food Is Always Dog-Friendly

All animals have different rates of metabolism due to the different rates of energy consumption which is the process by which food is broken down and turned into energy. Feeding human and other animal food to your dog may not be suitable as dog food. It does not matter how suitable the food is to you or to other animals.

Is alcohol dangerous to your dog?

wine is made from grapes that are toxic to dogs

Any type of alcoholic drink is nit dog food and although alcohol toxicity in dogs is rare it can be very dangerous if it happens. Some of these alcoholic drinks contain ingredients like yeast, hops, grapes and many more ingredients. It may not be known why grapes and hops are toxic to dogs but you do not want them intoxicating your dog. These items can cause violent reactions in your dog. To intoxicate an adult dog you would need far less alcohol than that needed to intoxicate humans. One reason for this is the size of dogs. Dogs can display symptoms of alcohol poisoning even if you feed him a simple rum cake.

Symptoms can range from vomiting, lack of coordination, breathing problems, potential kidney damage, fluctuations in temperature and can even lead to death. So, while you are enjoying your drink make sure that you are responsible and keep the drink out of the dog’s reach.

Apple Seeds

toxic dog food

Apple seeds contain a substance that is called amygdalin which is a form of cyanide. This substance is poisonous to not only your dog but also other living things. If your dog swallows these seeds the dog’s body will detoxify itself. For them to cause any issue to your dog he needs to have eaten and chewed large amounts that may cause it to enter into the bloodstream. This cyanide prevents blood from carrying oxygen in the body.

 To play safe make sure that you remove the seeds from the apple before feeding it to your dog.

Avocado as dog food

avocado not a very great dog food

There is a chemical that is found in Avocado that is called persin. When this substance is consumed in high amounts it can cause heart congestion, vomiting, and diarrhea in your dog.  But the main hazard is the pit that is found in avocado because it can actually choke your dog. In case your dog swallows an avocado pit you will need to call a vet as soon as possible.

This does not actually mean that your dog cannot eat avocado. Avocado can be dog food but make sure you monitor the amount that you give to him. Make sure that you only give him small amounts.

Toothpaste, chewy gum, candy, and mouth wash

chewy gum not for dogs
chewy gum

Candy contains xylitol that can lead to liver failure, loss of coordination, vomiting and even liver failure. Chewy gum can lead to intestinal blockage. Some gum also contains xylitol which is toxic.  Do not use human toothpaste or mouthwash on your dog as they contain fluoride which is extremely dangerous to dogs. Ask your vet about canine toothpaste that is made from water and baking soda. There is also a special mouthwash that is made for dogs. Consult your vet before using any of them for assistance.

Cat Food is not dog food 


Just as it dangerous to feed dog food to your cat it is also dangerous to feed cat food to your dog. There are proteins and fats found in cat food that specifically target the cat’s nutrition and that is why you cannot use this food as dog food. The fat and protein levels in a cat’s diet are too high for your dog. Even if your dog has an iron stomach the long term effects would create problems. Too much cat food in your dog’s diet can cause obesity, pancreatitis and even stomach upset.


Chocolate has caffeine and theobromine, that stimulate the nervous system and even speed the heart rate. The type and amount of chocolate your dog ingests will determine how sick the dog becomes. The dog’s weight will also determine how sick or not sick the dog becomes.

Ingestion of too much theobromine and caffeine in chocolate can result in vomiting, diarrhea, restlessness, increased urination, tremors, elevated heart rate, seizures, and death. Below is a list of most dangerous to least dangerous chocolate to dogs:

  • White chocolate
  • Cocoa powder
  • dark chocolate
  • milk chocolate
  • semisweet chocolate
  • unsweetened baker’s chocolate

Chocolate is a common product found in houses and dogs love the taste and smell of it. Make sure that you keep chocolate in a place that your dog cannot reach to stay safe.

Coffee, Tea & Other Caffeine

Caffeine is extremely dangerous to a dog and within 1-2 hours, your dog could be experiencing mild to severe hyperactivity, restlessness, vomiting, elevated heart rate and blood pressure, tremors, seizures, and death.

Cooked Bones

When it comes to bones, the danger is that cooked bones can easily splinter when chewed by your dog. Raw (uncooked) bones, however, are appropriate and good for both your dog’s nutrition and teeth.

Corn on the cob

While small amounts of corn are safe for a dog to ingest, giving your dog an ear of corn can be dangerous. If your dog is determined enough (which let’s face it, most dogs are) they will eat the cob and all. The cob can be a choking hazard and can cause intestinal blockage. This could be fatal to your dog.

Fat Trimmings

Cooked and uncooked fat trimmings can cause pancreatitis.


While garlic can be okay for dogs in very small amounts (and even beneficial for flea treatment), larger amounts can be risky. Garlic is related to onions that are toxic for dogs because it kills the dog’s red blood cell count, causing anemia. Signs may include weakness, vomiting, and trouble breathing.

Grapes & Raisins

Grapes and raisins can cause kidney failure for dogs. Even a small amount can make a dog ill. Vomiting is an early symptom followed by depression and low energy. We’ve heard stories of dogs dying from only a handful of grapes, so do not feed your pup this toxic food.






An ingredient in beer that can be toxic to your dog. The consumption of hops by your dog can cause vomiting, panting, increased heart rate, fever, and even death.

Human Vitamins

It isn’t recommended to give your dog one of your vitamins or supplements. Human vitamins often contain 100% of the recommended daily amount of various minerals. This could cause an overdose of a mineral for your dog.

The most dangerous vitamin is prenatal vitamins, which have a higher dose of iron and can cause iron toxicity in pets. If your dog ingests a bunch of prenatal vitamins (or other vitamins with a high dosage of iron) you should call your vet immediately.


In small amounts, the liver is great but avoid feeding too much liver to your dog. The liver contains quite a bit of vitamin A, which can adversely affect your pup’s muscles and bones.

Macadamia Nuts

Ingesting even small amounts of macadamia nuts can be lethal to your dog. Symptoms include muscle shakes, vomiting, increased temperature, and weak back legs. If your dog ingested chocolate with the macadamia nuts the symptoms can be worse.


Depending on how much your dog was exposed to can affect the level of poison. There isn’t much information out about dogs and marijuana but from what we can find, these are the common symptoms: slow response times, dribbling urine, heart rate change, neurological stimulation, hyperactivity, coma, and even death.

Milk & Dairy Products

While small doses aren’t going to kill your dog, you could get some smelly farts and some nasty cases of diarrhea. Milk and dairy products can cause digestive problems as well as trigger food allergies.

Onions & Chives

No matter what form they’re in (dry, raw, cooked, powder, within other foods), onions are some of the absolute worst foods you could possibly give your pup. They contain disulfides and sulfoxides (thiosulphate), both of which can cause anemia and damage red blood cells.


Bell Peppers are okay to feed dogs. Dogs are carnivores and prefer meat to vegetables, but there are some benefits to veggies. For example, green peppers are a low-calorie snack that is packed with vitamin C and beta-carotene.

Be sure to chop peppers into small pieces because the outer skin can be tough and difficult to chew. Pureeing or steaming the peppers makes them easier to consume and digest. As with most human food, don’t overdo it because too much could lead to sickness. It might go without saying, but never give your dog spicy varieties such as jalapenos or hot peppers!

Persimmon, Peach & Plum Pits

Pits/seeds from these fruits can cause intestinal issues in dogs. Additionally, peach and plum pits have cyanide, which is poisonous to dogs (and people!).

Raw Meat & Fish

Raw meat and fish can have bacteria which causes food poisoning. Additionally, some fish can contain a parasite that causes “fish disease” or “salmon poisoning disease.” Symptoms include vomiting, fever, and enlarged lymph nodes. Cooked fish is perfectly fine since the parasite is killed during the cooking process.

Rhubarb & Tomato Leaves

These contain oxalates, which can cause, drooling, vomiting, diarrhea, lethargy, weakness, tremors and bloody urine.


Just like salt isn’t the healthiest thing for humans, it’s even less healthy for dogs. Too much of it can lead to sodium ion poisoning, which may result in vomiting, diarrhea, depression, tremors, increased temperature, seizures, and even death.


This applies to any food containing sugar. Make sure you check the ingredient label for human foods – corn syrup (which is a less expensive form of sugar or glucose) is found in just about everything these days. Too much sugar for your pup can lead to dental issues, obesity, and even diabetes


Tobacco contains nicotine, which can be lethal to dogs. Symptoms include vomiting, abnormal heart rate, tremors, and weakness. Tobacco poisoning can present itself within 1 hour of ingestion.


Sugar alcohol found in gum, candies, baked goods, and other sugar-substituted items, xylitol, while causing no apparent harm to humans, is extremely toxic to dogs. Even small amounts can cause low blood sugar, seizures, liver failure and even death for your pup.


Just like yeast rises in bread, it will also expand and rise within your pup’s tummy. Make sure they don’t get any. While mild cases will cause gas, lots of farting and discomfort — too much of it could rupture their stomach and intestines. Yeast dough is also dangerous because as it ferments and rises it makes alcohol which can lead to alcohol poisoning.

Keep These Foods Out Of Your Dog’s Reach As Well

While these don’t fall in a particular category above, you’ll want to avoid them as well.

Old Food

You don’t like old and moldy food, so what makes you think your dog will? The bacteria in spoiled food contain all sorts of toxins that can be damaging to your dog’s health. Feed them the freshest and best, dog-approved food only!


If you feed your dog leftovers regularly, they won’t get a proper diet. If you do give them table scraps, make sure to take out any bones and trim down the fat.

Human Snacks

Chips can contain garlic and onion powder, cookies may contain raisins, chocolate or macadamia nuts, etc. Bottom line — there’s a reason there’s food and treats made especially for dogs.
