Plants and Foods That Are Toxic to Dogs

A Must-Know Guide for Every Dog Owner

As loving dog owners, we want to keep our pups safe—but many everyday foods and common garden or household plants can pose serious health risks to dogs.

At FurBuddies, we often see behavioural and health issues linked to accidental ingestion of toxic substances. Understanding what’s dangerous is one of the simplest and most powerful ways to protect your dog.

🚨 Why Dogs Get Into Toxic Things

Dogs explore the world with their mouths. Puppies, in particular, chew out of curiosity, boredom, or teething discomfort. Even well-trained adult dogs can be tempted by smells, textures, or stress.

Unfortunately, many toxic substances are:

• Easily accessible in homes and gardens
• Smell appealing to dogs
• Harmless to humans but dangerous to pets

🍫 Common Foods That Are Toxic to Dogs

Some of the most dangerous foods are everyday household items.

❌ Foods to Avoid Completely:

• Chocolate – Contains theobromine, which can cause vomiting, seizures, and heart issues
• Grapes & raisins – Can lead to sudden kidney failure, even in small amounts
• Onions, garlic, chives – Damage red blood cells and can cause anaemia
• Xylitol (artificial sweetener) – Found in gum and sweets and sugar free peanut butter; can cause liver failure
• Alcohol – Extremely dangerous, even in small quantities
• Avocado – Can cause digestive upset and toxicity
• Coffee & caffeine – Overstimulates the nervous system

⚠️ Other Risky Foods:

• Macadamia nuts
• Raw dough (can expand in the stomach)

🌿 Plants That Are Toxic to Dogs

Many popular houseplants and garden plants can be harmful—even deadly.

❌ Highly Toxic Plants:

• Oleander – Can affect the heart and be fatal

Even small amounts can cause symptoms ranging from mild stomach upset to severe poisoning depending on the plant and quantity consumed .

⚠️ Signs Your Dog May Have Been Poisoned

If your dog has ingested something toxic, symptoms may include:

• Vomiting or diarrhoea
• Drooling or foaming at the mouth
• Lethargy or weakness
