My dog has dry, flaky skin. What vitamins or supplements should I try?

Pet's info: Dog | Chihuahua | Female | 5 years and 6 months old | 10 lbs

Ever since moving to Texas from PA in July 2018, my dog has been having skin issues. She has extremely dry flaky sensative skin. I’ve tried adding oils to her food, or applying to her skin but it doesn’t seem to help as much as I’d like to see. If i should give her a vitamin, what kind/brand should i be looking for?

Thanks for using Petco Pet Education Center, formerly Petcoach! This is possibly due to skin allergies mostly due to the fact that it started after moving. Adding fish oil can be considered regardless to help with the dry skin. You can use the commercial kind for dogs. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for environmental allergies which require blood and/or skin tests. Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively!
