Computed from the published 0.2-0.5 mg/kg reference range, every 24h. Product strengths rarely split evenly, so round DOWN to the nearest practical dose and confirm with your vet.
Cats use a different amount
The published cat reference (vet consult) differs from the dog range. Never split the difference between species; check the cat page instead.
About Loratadine
Loratadine is an antihistamine, a class used to blunt allergic responses like itching, hives, and insect-sting swelling. You will see it sold as Claritin, and the label strength on the box is what matters for the math, not the brand. Reference data on this page reflects published veterinary sources, not a prescription for your dog.
What to have ready when you call the vet
Whether you are confirming a dose or reporting that your dog already got into something, the call goes faster with four facts ready: your dog's current weight, the exact product name and strength from the label, how much was given or eaten, and roughly when. With those, most clinics can answer in one call.
The safe habit
Confirm any medication decision with your veterinarian, who knows your dog's health history and other medications. VetDose shows published reference data, not prescriptions.
