According to the College of Veterinary Medicine, dogs should not have more than 10-15mg/kg of paracetamol per dose. For short-term use, this dose is given every 8 hours for a maximum of 5 days. In long-term therapy, particularly for severe cancer pain, some dogs have prescribed paracetamol at doses of 10mg/kg every 12 hours. In these cases, paracetamol might be combined with regular veterinary NSAIDs. You cannot give your pet paracetamol without knowing their exact weight and medical history, so you must consult with your vet before administering any pain relief to your pet. If your dog has a history of gastric ulcers or other digestive problems, it is important to weigh out the pros and cons of giving painkillers to your dog, and although paracetamol has weaker effects than other painkillers, it can still cause problems when given in excess. Your vet knows best which painkillers are suitable for your furry friend!
