Hello. Thanks for writing in. A 12 pound dog can usually take 2.5mg of Claritin daily. This should be 1/4 of a 10mg. You cannot give Claritin D, though. It has pseudoephedrine and can cause toxicity issues in dogs. Claritin is usually safe for dogs, but dogs with glaucoma or high blood pressure should not take antihistamines. In general, antihistamines do a poorer job of controlling severe itching in dogs. Benedryl may be a better choice and may help better with itching. I would use 1/2 of a 25mg tablet every 8-12 hours instead. Please let me know if you have any other questions. Hope this helps.
