Summer Cookout Safety Tips for Pet Parents 

Summer cookouts and backyard gatherings are a staple of warm weather. For most pet owners, the dog is already by the grill before anyone else shows up. American Humane Society put this guide together so pet parents can enjoy the day without second-guessing every plate that hits the table. 

According to the American Veterinary Medical Association, toxic food exposures in pets increase significantly during holidays and outdoor gatherings, and summer cookouts are among the highest-risk events of the year. Warm temperatures also speed up food spoilage and increase the chance of dehydration and overheating, particularly for dogs, who tend to eat fast and ask questions later. 

Some unsafe foods cause mild stomach upset and others can lead to serious, fast-moving emergencies. 

Cookout Foods That Are Toxic to Dogs and Cats 

Many popular cookout staples are unsafe for pets. The list below covers the most common risks: 

• Chocolate and cocoa desserts 
• Grapes and raisins 
• Onions, garlic and chives 
• Corn cobs 
• Cooked bones 
• Fatty meats and heavily seasoned scraps 
• Foods containing xylitol or birch sugar 
• Alcoholic beverages 
• Macadamia nuts 
• Caffeinated drinks 

The Problem with Table Scraps and Fatty BBQ Foods 

Hot dogs, burgers, ribs and heavily seasoned meats contain excess fat, salt and spices that dogs and cats struggle to digest. In dogs, high-fat table scraps can lead to pancreatitis, a painful inflammation of the pancreas that can escalate quickly without veterinary care. 

Cooked bones are a separate issue. They can splinter when chewed and cause choking or internal injuries. 

Why chocolate is dangerous for pets 

Chocolate contains theobromine and caffeine, two compounds that dogs and cats metabolize far more slowly than humans. Even modest amounts can cause serious harm. Dark chocolate and baking chocolate carry the highest concentrations and are the most dangerous. 

Signs of chocolate poisoning can include vomiting, diarrhea, increased heart rate, restlessness, tremors and, in severe cases, seizures. The severity depends on the type of chocolate, the amount consumed and the pet’s size. If you suspect your pet ate chocolate, contact your veterinarian right away. Don’t wait for symptoms to develop. 

Not all “healthy” foods are safe for pets 

This is where a lot of well-intentioned pet parents get caught off guard. Some foods considered nutritious for people are dangerous for dogs and cats. 

Grapes and raisins are among the most serious. Even small amounts can cause acute kidney failure in dogs, and the exact toxic compound still isn’t fully understood, meaning there’s no safe threshold to rely on. 

Avocado contains a compound called persin, which can cause vomiting and diarrhea in dogs and cats. 

Cherries — the pits, leaves and stems contain cyanogenic compounds. The fruit flesh is generally low-risk, but most people aren’t removing pits before offering a cherry to a dog. 

Citrus fruits — the juice and oils in lemons, limes, oranges and grapefruit can cause digestive upset and, in larger amounts, nervous system issues. 

Green tomatoes and tomato plants contain solanine, which is toxic to dogs and cats. Ripe red tomatoes are typically fine in small quantities, but the plant itself — stems, leaves and unripe fruit — is not. 

Onions, garlic, chives and leeks can damage red blood cells in both dogs and cats, leading to hemolytic anemia. This applies to all forms: raw, cooked and powdered. Garlic powder is especially concentrated and shows up in a lot of seasoned meats and marinades. 

Macadamia nuts can cause weakness, vomiting, tremors and fever in dogs, even in small amounts. 

If you’re unsure whether a food is safe, the general rule is: if it wasn’t made for a pet, don’t share it without checking first. 

Alcohol and pets don’t mix 

Pets should never have access to alcohol in any form — beer, wine, liquor or alcohol-infused foods. Animals are far more sensitive to alcohol than humans, and even small amounts can affect the nervous system and organs quickly. 

Symptoms of exposure can include vomiting, disorientation, weakness, difficulty breathing and dangerous drops in body temperature. During parties and picnics, unattended cups and spilled drinks are easy access points. Dispose of unfinished drinks promptly and let guests know not to share. 

What pets can actually eat at the cookout 

Including pets doesn’t have to mean excluding them from the food entirely. These are generally safe in moderation: 

• Blueberries 
• Seedless watermelon 
• Strawberries 
• Carrot sticks 
• Cucumber slices 
• Apple slices (no seeds or core) 
• Broccoli  
• Plain cooked boneless chicken 

Blueberries are a practical cookout snack for dogs — bite-sized, easy to hand off and naturally sweet. You can also freeze some of these options to help pets cool down during hot weather. 

Making your cookout pet-friendly 

Start with the basics: shade, fresh water and a secure spot away from the grill. Keep food at table height or locked in a cooler, and make sure trash is in a container with a lid. A knocked-over bin at a cookout can quickly turn into an all-you-can-eat buffet for a determined dog. 

Supervise pets near any open flame and skip the table scraps in favor of pet-safe treats. If the crowd gets loud or the gathering runs long, give your pet a quiet place to decompress away from the activity. 

If your pet gets into the food 

Contact your veterinarian or an emergency animal poison hotline immediately. Don’t wait to see if symptoms appear — call first. Early treatment significantly improves outcomes. American Humane Society encourages pet parents to speak with their veterinarian before introducing new foods as well, especially for pets with underlying health conditions. 

Have this information ready: 

• What your pet ate 
• Approximately how much 
• When it happened 
• Your pet’s weight and any symptoms already present
