Why does my dog's coat look dull with white flecks after brushing?

It's hard to see anything with the photos, however if the skin is flaking a few things could be happening: skin flaking can sometimes happen with parasites, so ruling out fleas or ticks is a good first step. Dry skin can also occur from over grooming (bathing too often which strips the coat of its natural oils), or from possible allergies/issues with diet. Using an aloe or oatmeal shampoo when bathing, adding some vitamin E or fish oil to the diet may help, however if the flaking continues, worsens, or you see irritation on the skin itself, having it checked by a vet is best.

I typically recommend using Free Form Snip Tips help keep the skin and coat healthy. If they are too expensive than you could add one teaspoon of coconut oil to her food and see if that helps. If not, than she should be examined by a vet to determine the cause of her skin and coat problem. She could have a skin infection and need an antibiotic. You could also bathe her with a medicated dog shampoo and see if that helps.

Sometimes diet, underlying allergies, or endocrine/metabolic disorders can change the overall condition of the coat. Make sure that Schmidty is eating a high quality diet and consider adding in a fish oil supplement. Welactin is one of my favorites ( http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=19121 ). Medicated shampoo my also be beneficial ( http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=21564 ). However, if Schmidt is drinking and urinating more than usual, experiencing lethargy, weight changes, or changes in his appetite, he should go to his vet because underlying organ/endocrine issues may be occurring. I hope that all goes well!

It looks like dandruff. However, if he's itchy or has any areas of skin that obviously have a rash, take him to your vet. If not, here's an article you may find helpful. https://www.petcoach.co/article/helpful-products-for-your-dogs-dry-skin/ Thanks for asking PetCoach!

The skin is unhealthy for some reason. This is usually caused by some irritation of the skin. The skin is most commonly irritated from allergies, fleas, mites, or inappropriate bathing. The irritation can then cause the skin to get infected with yeast and bacteria. The best thing you can do now is give a bath with a medicated dog shampoo (you can find this at the pet store). Follow the shampoo with an oatmeal or aloe conditioner labeled for dogs. Repeat the bath every other day for two weeks. If that's helping, then repeat the bath every week for a month. If all is good after that, then she should be OK to have a once monthly bath with normal dog shampoo. If the bath is not helping, or she's getting worse, then she needs to go to the vet. The vet will be able to determine if something else is wrong and if further treatment is needed.

Patchy hair coat can be due to a number of factors, including endocrine disease (such as hypothyroidism), allergies, bacterial or fungal or parasitic infection of the skin. I would recommend an exam at your vet so they can see the hair coat and skin. They may recommend testing such as bloodwork to screen for thyroid disease, or skin cytology to check for infection.

The flakes are most likely the dry skin coming off. You can give him an omega3 fatty acid supplement for sure. You need to use a product made for dogs. I found this one: https://www.amazon.in/Petvita-Ultra-Refined-Omega-3-Supplement/dp/B01IY1E28W/ref=sr_1_2?ie=UTF8&qid=1517925023&sr=8-2&keywords=dog+omega+3+fish+oil My favorite product is made by Missing Link: https://www.amazon.in/Missing-Link-Ultimate-Small-8-Ounce/dp/B0002W0S4Y/ref=sr_1_1?s=pet-supplies&ie=UTF8&qid=1517925070&sr=1-1&keywords=missing+link+dog Either of those would be fine. Don't bathe him too much unless you have a soap-free shampoo. You may be drying out his coat by bathing too frequently. With soap-free shampoo you can bathe often without fear of drying his skin. I like this one: https://www.amazon.in/Nap-India-Virbac-Episoothe-Shampoo/dp/B06XHQMR14/ref=sr_1_11?s=pet-supplies&ie=UTF8&qid=1517925172&sr=1-11&keywords=dog+shampoo+soap+free Hope this helps. Best wishes.
