My old girl Pepper has a swollen back foot. I think it's a sprain as it's just swollen and she's still putting some weight on it but it's definitely pinker. I just want to make sure I have the dosage for infant ibuprofen correct. I did the math for a dose of 20 mg/kg using infant ibuprofen 100 mg/ 5 ml. She weighs 580 grams or 0.580 kgs so she should get 0.58 mls? I'm not sure if my math's correct or if I'm missing something. Thanks!
