Foods that make dogs sick include chocolate, grapes, onions, garlic, xylitol (sweetener), avocado, alcohol, caffeine, cooked bones, fatty foods, yeast dough, macadamia nuts, and salty items, which can cause symptoms from vomiting and diarrhea to organ failure, requiring immediate vet attention for toxic ingestion.
Common toxic foods for dogs
Common examples include certain human foods (like chocolate or grapes), some medications, and mild household toxins. Removing these substances quickly through controlled vomiting can sometimes prevent absorption and reduce potential harm.
Vomiting or diarrhea for an extended period may be symptomatic of many things, including pancreatitis, infections, ingestion of foreign material, accidental poisoning, or parasites, all of which require urgent veterinary care. Dog owners should also be alert for signs of lethargy.
Other Foods Harmful to Dogs
Dairy products can upset your dog's digestive system and cause diarrhea as well as food allergies. Ingestion of just a few macadamia nuts can cause weakness, paralysis and lack of coordination. Avocados contain persin, which can cause mild stomach upset in dogs.
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.
Signs to Watch For
Many dogs experience vomiting, diarrhea, drooling, or a sudden loss of appetite. In more serious cases, symptoms like lethargy, tremors, or seizures may occur. If your shows severe signs or does not improve within a few hours, immediate veterinary care is needed.
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.
Poisons – like rat poison and antifreeze. These are the silent killers and can attack many body organs. Caustics – caustic substances like bleach, household cleaners and petrol, these are corrosive materials. Foreign bodies – these are objects like balls and toys, which dogs often swallow whilst chewing or playing.
What Are the First Signs My Dog Might Be Sick?
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.
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).
5 Common Reasons for Dog Vomiting
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.
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.
Common foods that are toxic and can potentially kill dogs include; grapes, raisins, avocados, chocolate, xylitol (an artificial sweetener), fruit stones and pips (including apple cores and plums), onion, garlic, macadamia nuts, raw eggs, alcohol, caffeine, bread dough, liver, raw fish, milk and cheese.
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.
There isn't a single definitive "Top 10 Poisons," as it varies by context (household, deadliest known, etc.), but common exposures involve pain relievers, household cleaners (bleach, detergents, antifreeze), antidepressants, and personal care items, while historically potent poisons include Botulinum toxin, Arsenic, Dioxin, and Tetanus toxin; the deadliest natural substance is often cited as Botulinum Toxin.
Treatment with more than one drug at a time will often improve a dog's response to sedation. Possible oral sedative combinations include: acepromazine and Telazol powder (an anesthetic) acepromazine and diazepam (an anti-anxiety drug)
The most commonly surrendered dog type is the "pit bull type" (including mixes), often due to negative stereotypes, breed-specific legislation, and high energy levels, followed by other popular breeds like German Shepherds, Huskies, and Labrador Retrievers that may not fit owner lifestyles. Breeds like Staffordshire Bull Terriers (especially mixes) also top surrender lists in some regions like Australia.
The seven second rule. Put the back of your hand on the pavement. If you cannot hold it for seven seconds, it is too hot to walk for your dogs. This rule also applies to dogs riding in the bed of a pickup truck.
Signs of poisoning in dogs that need emergency care include collapse, seizing, excessive drooling, breathing problems, and severe vomiting or diarrhea. These symptoms indicate your dog may have ingested something toxic and needs quick veterinary attention.
Dogs should not eat onions, garlic, leeks, and chives (Allium family) as they cause anemia; avocados due to potential toxicity and blockage from pits; green parts of tomatoes and potatoes, and unripe tomatoes as they contain toxic solanine; and corn cobs which are a choking/blockage hazard, though cooked corn kernels are fine in moderation. Wild mushrooms are also a major risk, and some sources suggest limiting peas due to links with heart disease.
Symptoms of rat poisoning in dogs
Weakness and lethargy. Vomiting or coughing blood. Nose bleeds. Bleeding from the gums or pale gums.
