Piriton is an antihistamine commonly used in dogs. Unfortunately, we are legally prohibited from providing or recommending dosage information the absence of a physical exam and a patient-veterinarian-client relationship. You can contact your veterinarian and request this information. Piriton is given based on weight so you will need a current weight to get an accurate dose.

    I would not recommend giving Charlie Piriton. This should only be given to dogs under veterinary supervision, who would give the correct dose depending on his weight and age. It may not be safe to give to puppies either. Chewing on the back is a sign of itchiness, which could be due to a couple of things. The underlying cause has to be treated in order to relieve the itching. This biting can be caused by fleas, mites, ringworm, or allergies. If he isn't up to date on his flea treatment, he will need a spot on treatment such as Advantage or Revolution. You will need to disinfect the environment as well. If he is up to date on his flea treatment, I recommend taking him into the vet for an exam. The vet can do blood tests, skin scrapings, and use a Wood's lamp to diagnose allergies, mites, and ringworm. Once the cause of the itching is found, the vet can prescribe the appropriate treatment. I recommend taking him into the vet today or tomorrow during normal business hours.
