Q. Dog has dry ears and it itches him. Any recommended soothing lotions??
A. I will answer this question as if you are speaking of the inside of the ears (not the external). Most dogs ears aren't dry unless they have other skin issues such as skin allergies, which can be seasonal or year around and caused by many different things, such as foods, environment, dust, grass, pollen, and products (shampoos, perfumes, etc). Check in the ears for waxy build up. The ears should be clean of any wax and dry. If they have build up, I would take a cotton ball, and soak half of it in a dog ear cleaning solution. This solution should be made specifically for dogs, and your local vet would most likely sell the appropriate brand.
I would address any possible skin allergies, if they do not have any other skin issues, then looking inside the ears and cleaning with a good ear cleaner (should be alcohol free---because alcohol is very drying) If the ear scratching continues regularly then bring him/her into the vet to have a proper ear exam.
