Foods that are toxic to dogs
Did you know that many of the common foods that we humans enjoy can be harmful to our dogs? It's not always easy to know what's safe, so here's a guide to foods that can be dangerous for your dog. If your dog has eaten any of these, it's always best to get advice from a vet.
Chocolate and cocoa
Chocolate and cocoa are toxic to dogs because they contain theobromine. Dogs can't break down theobromine, which can lead to poisoning. The severity depends on factors like the cocoa content, how much was eaten, and your dog's age and weight.
If your dog eats chocolate, call your vet straight away for advice, even if they seem fine. Symptoms usually appear within 2-6 hours, but can take up to 24 hours. Watch for vomiting, shaking, excessive drooling, rapid heartbeat, diarrhoea, cramps, and tummy pain (which might show as a reluctance to eat).
Raisins and grapes
Both raisins and grapes are very dangerous. Eating them can lead to acute kidney failure. All types of grapes and raisins are risky, and some dogs are more sensitive than others. There's no clear link between the amount eaten and the severity of poisoning.
Acute kidney failure is serious and needs immediate action. Sadly, the mortality rate is high even with prompt treatment. Contact a vet immediately if poisoning is suspected. Symptoms include increased thirst and urination, vomiting (2-48 hours after ingestion), diarrhoea, tummy pain, lethargy, and weakness.
Onion
Onions (raw or cooked) contain allicin, which is toxic and can cause anaemia. It's hard to say exactly how much causes poisoning. This is especially important if you give your dog leftovers, as human food often contains onions. Symptoms can include diarrhoea, vomiting, cramps, loss of appetite, breathing difficulties, pale gums, and tummy pain.
Nuts
Nuts can block your dog's throat or intestines. Salty nuts can also cause salt poisoning. Some nuts, like bitter almonds and macadamia nuts, are poisonous. Symptoms to watch for include loss of appetite, vomiting, bloody stools, impaired liver function, diarrhoea, stomach upset, wobbliness, lethargy, and paralysis.
Yeast dough
If your dog eats raw yeast dough, it will ferment in their stomach, producing alcohol and making them drunk. This can be a life-threatening condition and is very unpleasant. Always keep dough well out of reach. If your dog has eaten dough, monitor them closely to ensure they don't harm themselves. Some dogs may also act aggressively if they feel unwell. Symptoms can include wobbliness and unsteadiness.
Salt
If your dog drinks salt water or eats salty food, they can suffer from salt poisoning. Symptoms can include diarrhoea, vomiting, stiffness, and cramps.
Spices
Some spices can be deadly, especially garlic and onion powder. Avoid giving your dog chamomile, leeks, and chives too.
Xylitol
Xylitol is commonly found in toothpaste, chewing gum, diet products, and sweets. It's dangerous as it lowers blood sugar levels and can cause poisoning. A dog's tolerance varies, so it's best to avoid giving them anything containing xylitol. Symptoms include vomiting, lethargy, tremors, convulsions, and loss of consciousness.
Fungi
Just like in humans, some fungi are fatal or can make your dog very ill. Be careful when out and about and watch out for your dog eating fungi. If you suspect they've eaten poisonous mushrooms, contact a vet as soon as possible. Symptoms usually include vomiting, diarrhoea, and trembling.
Avocado
Avocados contain persin, which is toxic to dogs and can damage their heart and gastrointestinal tract. Common symptoms are vomiting, apathy, and diarrhoea.
Broad beans
Broad beans can cause vomiting, diarrhoea, and tummy pain in dogs.
Contacting the vet
If you're worried your dog has eaten something potentially poisonous, always consult a vet. It's helpful if you know what they ate and how much. Poisoning can happen quickly, so it's better to consult a vet than wait too long. With Lassie insurance, you have 24/7 access to our online vet service, FirstVet.
