Thanks for using Petco Pet Education Center, formerly Petcoach! This is likely due to allergies. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided.

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!

    This can be from an environmental allergy or a low thyroid level. Your vet can do a blood test to monitor the thyroid level and see about special shampoo or medication to help control further allergies

    Any time they are itching around the tail area, it may be from a flea allergy. You can check for fleas first and get medication to control it if needed. With all the scales you can get a medicated shampoo to bathe him in the help loosen up the scales and brush it out of the fur. This may be a sign of a skin infection that will need antibiotics to fully treat.

    Thanks for using Petco Pet Education Center, formerly Petcoach! This is possibly due to allergies. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided. A secondary infection is likely and also needs to be addressed.
