What causes a senior dog's coat to change from soft to wiry?

Hi there and thank you for using Pet Coach! The cause of hair thinning could be from multiple causes. Allergies, metabolic disease, skin infection, hair coat thinning due to temperature change, etc. are all possibilities. I would recommend using a shampoo such as Douxo PS Calm shampoo. I would also recommend using Welactin Omega 3 fish oil and essential 6 spot on by dermoscent. I hope this helps! If the hair thinning worsens or does not improve, I would recommend having your vet take a look at Twixie for further diagnostic and treatment recommendations.

There are many nutrients required for healthy skin and coat color and any one of these can result in dulling and fading of the coat. Ensure he is receiving a well balanced, complete diet and consider converting to a skin support range in order to exclude this if he has no other signs of poor digestion/food absorption (chronic diarrhea or weight loss). Certain hormonal conditions such as cushings and thyroid disease can also affect coat condition and color, a full vet check and blood panel would be recommended to investigate this

If your vet thinks this may be an adrenal problem you may want to discuss testing first. Cushing's disease can cause coat changes and increased thirst, and is treated with medication, typically a medication called trilostane. It's also possible that R2's thyroid disease is the cause if her thyroid levels have not been checked recently. If the coat changes are due to an endocrine disease like Cushing's or hyperthyroidism and her coat is shaved it might not grow back well. Talk to your veterinarian about what test they would recommend.

Minor skin and coat changes can be normal in older dogs, however it is always best to rule out anything underlying such as a metabolic issues, especially if you are seeing any other changes such as weight gain/loss, irritation of the skin, increases in thirst/urination, or changes in eating habits as these can all indicate a metabolic rather than an aging problem. If he checks out healthy, it may just be that he got the genetics for having a thinner coat, whereas some dogs may go gray faster or not at all, etc. Keeping the area groomed and free of mats may help keep any remaining hair from being pulled out, and in some cases a supplement such as fish oil or vitamin E may help with overall skin and coat health.

Hi there and thank you for using pet coach to address your concern. For dandruff, I recommend using a product called Krillex shed free chews, which can be found online quite easily. I have had amazing results using this supplement. I would recommend using this and allow for at least 3 months to see an improvement. I hope this helps! Please let me know if you have any further questions or concerns and I would be more than happy to help you further.

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.
