5 Foods You Should Never Feed Your Dog


Welcome back to the Sun Valley Animal Center blog! In our recent blog posts, we looked at some of the best people foods that are safe to share with your canine companion. While there are a plethora of foods like carrots, apple slices, sweet potatoes, and unseasoned, deboned chicken and turkey that are safe and nutritious to feed your dog, there is a myriad of foods that are toxic to them. While dog lovers enjoy sharing their food with their pups, these are the foods that you should never give them, as they can damage your dog’s digestive system and trigger severe health problems. Here are the foods to avoid feeding your furry family member:

Grapes & Raisins

Many dog lovers mistakenly feed their pups grapes and raisins as an easy-to-chew treat. These snacks are actually very toxic for your pup and can cause kidney failure. While the toxic substance that causes canine kidney failure is still being researched, it is best to avoid sharing these treats with your dog. Make sure to keep grapes and raisins stored in an area that is inaccessible to your dog.


Avocados contain persin, a fungicidal toxin that is mildly poisonous to dogs. While avocados are not as toxic to pups as some other foods, they can cause vomiting and diarrhea, which can dehydrate your dog and decrease their energy levels. The most dangerous aspect of the avocado is the pit which presents a choking hazard to your dog. It’s best to dispose of the pit in a wastebasket that your dog cannot access. Additionally, if you grow avocados at home, make sure your dog can’t get to them.


With Halloween just around the corner, chocolate candy will be a common feature in households across the country. Chocolate contains a substance called methylxanthines found in the cacao seeds used to make chocolate. While dark chocolate contains the highest level of this toxic substance, milk chocolate and white chocolate contain lower amounts. If your dog ingests chocolate, it can cause vomiting, diarrhea which leads to dehydration and excessive thirst. Additional symptoms include heavy panting, frequent urination, shaking and tremors, hyperactivity, rapid or abnormal heart rate, seizures, and in the worst case, death. It’s best to keep all chocolate and chocolate products stored in high, secure places where your dog can’t reach it. Be extra mindful about where candy bowls are placed around the house this holiday season.

Garlic & Onions

These staple foods are commonly found in kitchens, but should never be given to your pup. Garlic and onions contain enzymes which cause gastrointestinal issues that can wreak havoc on your dog’s red blood cells. Some recommend using garlic as a flea deterrent, but this simply does not work and should not be a part of your dog’s diet.  

It’s best to avoid these feeding your pup these foods altogether. If your dog needs immediate care for ingesting a toxic food, call us immediately.  If you have questions about your dog’s diet and would like nutrition guidance, contact Sun Valley Animal Center, the nation’s Top Rated Local® veterinary hospital and animal clinic, where your pet’s health is our main priority.
