Food That Is Toxic for Dogs
There's no single "number one" food, but chocolate, grapes/raisins, and foods containing the artificial sweetener xylitol are among the most dangerous and common toxic items, causing issues from vomiting and seizures to kidney failure or death; other major threats include onions/garlic, alcohol, and fatty/cooked bones that can splinter. Always contact your vet immediately if your dog eats anything suspicious.
Three toxic types of meat for dogs include fatty, processed meats (like bacon, sausage, ham) due to salt/fat causing pancreatitis and sodium issues; seasoned meats with onions/garlic (allium) that damage red blood cells; and cooked bones, which splinter and cause internal damage or blockages, potentially requiring surgery. Raw meats can also carry harmful bacteria like Salmonella or E. coli.
Dogs should not eat grapes, raisins, currants (can cause kidney failure), avocados (persin toxin), cherries, plums, peaches, apricots (pits/seeds contain cyanide & are choking hazards), or citrus fruits like lemons/limes (cause stomach upset). Also avoid the green parts of tomatoes and wild berries, and be cautious with seeds/pits from many fruits due to cyanide and obstruction risks.
A small bite of avocado flesh is usually safe for most dogs. However, large amounts can lead to gastrointestinal upset, especially for dogs with sensitive stomachs or a history of pancreatitis.
Healthy fruits for dogs
Avocados are high in fat, which can cause pancreatitis, an inflammation of the pancreas, a digestive organ. In some cases, this condition can even be fatal. Some dogs can develop pancreatitis even if they only eat a small amount of avocado pulp.
Although blueberries are a healthy treat, their small size could present a choking hazard for some dogs. Eating too many could also result in digestive upset. Cavities in dogs are rare but may form if they eat too much sugar. Blueberries may be healthy, but they also contain sugar, so feed in moderation.
Heartworm disease is among the top silent killers of dogs and cats, and it's a slow and insidious disease which gradually incapacitates them. By the time pet owners notice the giveaway signs of this disease, serious damage may already have been caused.
The seeds contain cyanide.
Apple seeds have trace amounts of cyanide, which can be toxic in large quantities. Your dog would have to eat a lot of seeds to have a problem—but it's still better to be safe and remove the seeds before giving any apple slices to your dog.
The leading cause of death in dogs, especially older dogs, is cancer (neoplasia), affecting about 1 in 4 dogs, similar to humans, with specific breeds at higher risk. Other significant causes include old age, heart disease, digestive disorders (like bloat), infectious diseases (like Parvo), and trauma, with sterilization influencing risks for cancer and infections.
High fat content: Fatty cuts of steak or ground beef that isn't drained of fat can be bad for dogs. Too much fat can lead to digestive upset (vomiting or diarrhea) or even pancreatitis. Bone hazards: Steak bones can also pose a major choking hazard, which is a serious emergency.
The healthiest dog food depends on your dog's specific needs, but top veterinarian-recommended brands known for science-backed nutrition and meeting AAFCO standards include Hill's Science Diet, Royal Canin, and Purina Pro Plan, offering options for life stages and health conditions. For sensitive dogs or allergies, limited ingredient diets (LID) from brands like Prime100 (single protein, human-grade) or raw/air-dried diets from Eureka (high meat, organs) are excellent choices, focusing on whole, digestible ingredients for better gut and skin health, but always consult your vet first.
The 90/10 rule for dogs means that 90% of their daily calories should come from a complete and balanced dog food, while only 10% should come from treats, chews, and table scraps, preventing weight gain and ensuring proper nutrition. This guideline helps owners manage treat portions, preventing unbalanced diets and health issues like obesity, joint problems, and diabetes, as treats can be surprisingly high in calories, even healthy ones.
The best vegetables for dogs are nutrient-rich, low-calorie options like carrots, green beans, sweet potatoes, pumpkin, and spinach, providing vitamins, fiber, and antioxidants, but should be served cooked (for starchy ones) or raw (carrots, green beans) in moderation as treats. Always avoid toxic veggies like onions, garlic, and grapes, and remember treats shouldn't exceed 10% of their diet.
Metaldehyde poisoning is extremely serious and is usually fatal without urgent treatment. Metaldehyde is the most common known cause of dog deaths in cases referred to the Veterinary Poisons Information Service (VPIS).
The 3-3-3 rule for dogs is a guideline for the adjustment period after adoption, outlining three phases: 3 Days (decompression, feeling overwhelmed/scared), 3 Weeks (starting to settle in, learning routine, personality emerges), and 3 Months (feeling secure, bonded, and truly at home). It helps new owners manage expectations and be patient as their rescue dog transitions, emphasizing calm energy, routine, and space in the early days to build trust.
Blue-Green Algae (BGA) can contain harmful biotoxins that cause rapid (often within minutes) and severe seizures or liver failure. These are cyanobacteria that can be found in lakes, ponds, and rivers.
A red flag dog behavior signals deep fear, stress, or potential aggression, going beyond normal misbehavior, and includes intense growling/snapping without cause, sudden aggression in a calm dog, persistent hiding, resource guarding (food aggression), freezing, destructive behavior linked to separation anxiety, or signs of extreme anxiety like trembling, lip-licking, and tail-tucking, indicating underlying problems needing professional intervention.
Dogs should not eat grapes, raisins, currants (can cause kidney failure), avocados (persin toxin), cherries, plums, peaches, apricots (pits/seeds contain cyanide & are choking hazards), or citrus fruits like lemons/limes (cause stomach upset). Also avoid the green parts of tomatoes and wild berries, and be cautious with seeds/pits from many fruits due to cyanide and obstruction risks.
Here is a list of healthy fruits and vegetables to treat your dog with, as well as a few yummy recipes for homemade dog treats!
Dogs should not eat holly berries, mistletoe berries, elderberries, juniper berries, gooseberries, pokeweed berries, nightshade berries, or yew berries, as these contain toxins (like saponins or hydrocyanic acid) that can cause vomiting, diarrhea, or more severe illness; also avoid cherry pits and stems due to cyanide. While many common berries (blueberries, raspberries) are safe in moderation, always check with your vet and steer clear of wild or unknown berries, especially those growing in hedgerows.
Persin is a fungicidal toxin present in the avocado. Persin is an oil-soluble compound structurally similar to a fatty acid, a colourless oil, and it leaches into the body of the fruit from the seeds.
Many pet owners wonder "can dogs eat onions?" while preparing meals or sharing table scraps. The answer is a firm and absolute no – onions are highly toxic to dogs and can cause serious health problems. Onion poisoning can happen quickly and sometimes with just a small amount of this common kitchen ingredient.
Yes and no. Dogs can eat tomatoes in moderation, but only ripe ones. Don't offer your dog tomatoes in large quantities or frequently and make sure to avoid feeding them green tomatoes as they contain substances that can be harmful to them.
