When a Pomeranian develops bald patches on both sides of the body, two conditions may come up in the conversation: Alopecia X and Cushing’s syndrome. The coat can look similar, but the health implications and investigation can be quite different.
The useful distinction in Alopecia X vs Cushing’s is the whole dog, not the color of the skin. Changes in drinking, urination, appetite or strength deserve as much attention as the missing fur. A photograph cannot settle the diagnosis.
Why the coat alone does not provide the answer
Alopecia X involves hair-cycle disruption. Molecular research investigates affected follicles; it does not diagnose Cushing’s syndrome.
Cushing’s syndrome involves excessive exposure to glucocorticoids. In naturally occurring cases, this commonly relates to a pituitary or adrenal disorder. Exposure to steroid medication can also produce a Cushing’s-like syndrome. Your veterinarian therefore needs a medication history, including ear, eye and skin products—not just tablets. AAHA’s explanation of canine hypercortisolism describes these different causes.
Owners sometimes compare their dog with a dramatic before-and-after image online. That may help them notice a change, but it cannot show the examination findings or test results behind the photograph. Keep that image as a question for the appointment, not as proof.
Alopecia X vs Cushing’s: clues worth reporting
The following observations help your veterinarian decide what to investigate. They are clues, not a checklist for diagnosing your dog at home.
- Drinking and urination: report noticeably more water intake, overnight requests to go outside or new accidents.
- Appetite and breathing: mention persistent hunger or panting that seems unusual for your dog.
- Body shape and movement: a fuller-looking abdomen, loss of muscle or difficulty with familiar activities matters.
- The skin itself: describe whether the change is simply thinning or also involves sores, discomfort or recurrent problems.
These systemic features can increase concern for Cushing’s, although affected dogs do not all have the same presentation. AAHA’s clinical assessment guidance supports interpreting the pattern as a whole. Their absence should not be treated as a definitive rule-out.
If you are unsure when changes began, review older videos of walks and photographs of your dog standing. A dated timeline is more useful than trying to reconstruct several months from memory. Our article on early coat changes in Pomeranians can help you organize that history.
What testing can—and cannot—tell you
Your veterinarian may start with an examination, blood count, chemistry profile and urine testing. These help establish the context for more targeted tests. An abnormal routine blood result does not, on its own, answer the Alopecia X vs Cushing’s question.
When clinical suspicion is appropriate, adrenal testing may follow. The AAHA panel generally favors a low-dose dexamethasone suppression test as an initial diagnostic test. An ACTH stimulation test or additional investigation may be appropriate in other circumstances. Stress and concurrent illness can affect results, so test selection and timing matter. See AAHA’s guidance on diagnostic testing for Cushing’s.
A useful question is: “What finding would this test clarify, and how would the result change the plan?” That allows you to understand a staged investigation without expecting one broad hormone panel to answer every question.
Why the distinction changes the care plan
For a dog being assessed for a systemic hormone disorder, coat regrowth is only part of the picture. The veterinarian also needs to address the dog’s overall health. Conversely, treating an unexplained bald patch as a confirmed hormonal disease can send the investigation in the wrong direction.
Do not start, stop or alter a prescribed steroid or endocrine medication because of an online comparison. Bring the product names and instructions to your appointment. If you are seeking another opinion, include the actual laboratory reports with units, reference ranges and test dates.

Common questions
Does dark skin mean my dog has Cushing’s?
No. Skin color is not enough to distinguish these conditions. Ask your veterinarian to interpret it alongside the distribution of hair loss, the examination and any appropriate tests.
My dog seems well. Can I skip the examination?
Feeling well is reassuring information to share, but it does not explain the hair loss. Arrange an assessment and agree on what to monitor while the cause is investigated.
What should I bring to the appointment?
Bring a coat timeline, clear photographs, all medication and supplement labels, previous test reports, and notes about daily habits. Include what has stayed normal as well as what has changed.
