My dog's fur has scabs and clumps. Allergies, new food, or move?

While it's possible for food sensitivities to change over time and cause skin issues, since Mariner is a senior pup it may be time for a senior wellness exam. Scabbing on the skin could be due to a number of things including the aforementioned food allergies, environmental allergens, skin infections, parasites and even metabolic changes. A complete examination of his coat plus some general bloodwork may alert you to the cause of his scabbing. In the meantime, an Elizabethan (cone) collar, if it doesn't interfere with his service work, or a T-shirt to protect the affected area, may help prevent him from scratching or chewing and give the area some time to heal. It will also keep Mariner from introducing more bacteria into the site which can lead to an infection.

These scabs could be due to itching from something such as fleas, mites, ringworm, or allergies. If he isn't up to date on his flea treatment, I can give you one for him. First, I would give him Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. If he is up to date on his flea treatment, I recommend taking him into the vet for an exam today or tomorrow. The vet can do blood tests, skin scrapings, and use a Wood's lamp to diagnose allergies, mites, and ringworm. Once the cause of the itching is found, the vet can prescribe the appropriate treatment. I hope this helps!

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. This does look severe and it would be best to have him evaluated by your veterinarian for further assessment and treatment. 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!

It is really hard to tell from a photo alone what is going on in the skin, however it is evident that something is causing inflammation of the skin. Dermatitis can be caused by many things including infection, irtitants, parasites, allergies or metabolic conditions. With you being away stress may have had a role in this. Ask your friend if they have given any new foods or used new shampoo? I would advise you to get to a vet for a skin exam in the next day or 2 as it is best to nip this sort of thing in the bud before it spreads.

What you can do in the meantime is use an e-collar to prevent further self-injury.

Hello, thank you for your question about Max. Based on the photos that you've attached and Max's symptoms it is possible that he has an underlying skin problem such as allergies or infection. Dogs can have underlying allergies to many things both dietary and environmental. I would recommend having him evaluated by your veterinarian so that they can examine the areas and determine the need for additional testing such as a skin scrape or impression to look for bacteria and cells. Hope this helps, good luck!
