I’m so sorry to hear that your dog is in discomfort. It sounds like he may have a skin condition that needs to be addressed.
I would recommend taking him to the veterinarian for a checkup and then following any treatment plan that your vet prescribes.
In the meantime, you can try to soothe his skin by bathing him with a gentle, hypoallergenic shampoo.
You can also apply a moisturizing cream or ointment to the affected areas. Be sure to check with your vet to make sure that the treatment you are using is safe and appropriate for your dog.
