Dogs are also sensitive to the effects of paracetamol where it can cause extensive liver damage leading to failure of the liver; a life-threatening complication. Early signs can include vomiting and reluctance to eat, which progress to diarrhoea, abdominal pain, jaundice, bleeding and collapse.
Dogs are less sensitive to paracetamol than cats. A 20kg dog would need to ingest over seven 500mg tablets in order to suffer toxic effects. In cats, one 250mg paracetamol tablet could be fatal.
Signs of toxicity from acetaminophen may develop within 1–4 hours of ingestion. Acetaminophen can cause liver damage or decrease the red blood cell's ability to carry oxygen (methemoglobinemia). Dogs may become depressed or weak, with rapid breathing, a high heart rate, panting, abdominal pain, vomiting or drooling.

"Paracetamol is licensed in dogs as Pardale V for 5 days. The dose in Pardale V works out at 33mg of paracetamol for every kg of body weight, three times daily. The listed dose in most vet formularies is 10mg/kg twice to three times daily," Nick explains.
The symptoms of opioid overdose for a police dog are similar to a human overdose. Symptoms may appear anywhere from 1 to 30 minutes after exposure, depending on how much of the drug was ingested, and by what route.
Potential toxicity should be assessed and a toxicologist consulted when: >200 mg/kg (or 10 g) ingested over a 24 hour period. >150 mg/kg/day (or 6 g) ingested over a 48 hour period. >100 mg/kg/day ingested over a 72 hour period.
Acetylcysteine has long been recognized as an effective antidote, via oral or intravenous administration, minimizing the risk and severity of acute liver injury if administered sufficiently early after a paracetamol overdose.
Intravenous acetylcysteine is the antidote to treat paracetamol overdose and is virtually 100% effective in preventing liver damage when given within 8 hours of the overdose.
No. Milk is unlikely to be helpful in the vast majority of poisoning situations and can sometimes make things worse. Most pets are lactose intolerant and giving milk can cause or worsen stomach upset symptoms.
Clinical signs of poisoning in a dog may include: Gastrointestinal signs: vomiting, diarrhea, extreme salivation, loss of appetite, and nausea or dry heaving. Internal bleeding: indicated by pale gums, a racing heart, coughing up or vomiting blood, weakness or lethargy, or a dog's falling over or collapsing.
Acetaminophen/Tylenol
Poisoning can occur from a single exposure to a large dose or from chronic exposure to a low dose. Acetaminophen poisoning in dogs causes injury to the liver and, in high enough dosages, even liver failure. Clinical signs can include lethargy, loss of appetite, belly pain, and jaundice.
No dog should be given paracetamol without being prescribed it by a vet. But if your dog does accidentally ingest paracetamol, the effects can vary depending on the size of the dog. For instance, a dog that weighs 20kg would only suffer toxic effects after eating seven 500mg tablets.
Paracetamol is sometimes prescribed for your dog however the dosages will reflect the weight of your best friend. Giving a 500mg tablet to a Miniature Poodle for example, could cause ill effects. It is unlikely to be fatal but could case damage to the liver and red blood cells so always better to be safe than sorry.
The most commonly used dose rate in dogs is 10 mg/kg orally every 12 hours. NEVER go above this does rate without first checking with your veterinarian.
25% of poisoned pets recover within two hours. Of the pets that take longer to recover, many can be treated at home with the advice of your veterinarian or with advice from the ASPCA Poison Control Center (telephone 1-888-426-4435).
Always take the dog to the vet as soon as possible, as your vet may need to pump your dog's stomach (called "gastric lavage") or administer activated charcoal to bind up any toxins in the stomach.
Tremors can be a sign that your dog has eaten something poisonous, like chocolate or the sugar substitute xylitol. If you suspect that your dog has ingested something toxic, contact a nearby vet or animal emergency hospital immediately.
If your pet has ingested a poison, try to rinse or wipe out the mouth with a damp towel/flannel. Do not give your pet anything to eat or drink before speaking with the Animal Poisons Helpline or a vet. We receive a lot of calls with pet owners asking how to induce vomiting in dogs.
Without treatment, death from toxicity occurs 4 to 18 days later. Liver failure, kidney failure, pancreatitis, low blood sugar, lactic acidosis.
Paracetamol overdose is one of the leading causes of liver failure. Scientists have known for decades that paracetamol in large amounts is toxic the liver, but until now its mechanism of poisoning has eluded them.
