Can you use normal antihystamine cream for your Labs itchy bum?

It is not advisable to use normal antihistamine cream on your Lab's itchy bum. Your dog may ingest the medication by licking the area, and many commonly-used antihistamines are toxic to dogs.

If your Lab is experiencing an anal gland issue or skin allergy the best course of action is to take them to the vet. They will be able to prescribe the correct medication and dosage ensuring your dog is not put in any danger.
