Recurring Dog Health Issues: Symptoms, Causes & Genetic Tests

When Your Dog’s Symptoms Keep Returning: Is It Time to Look Deeper?

Another episode of diarrhea. Another anal gland appointment. Another prescription for a problem that improves briefly, then returns.

For dog owners, this cycle can be frustrating, expensive, and worrying. You want your dog comfortable, but you also want an explanation: Why does this keep happening, and what are we doing to investigate the cause?

That is a reasonable question. For English Goldendoodles, Bernedoodles, and other dogs, a thoughtful care plan should consider medical history, nutrition, examination findings, and relevant inherited risks.

However, genetic testing, probiotics, medication, and imaging serve different purposes. Understanding those differences can help families ask better questions and make informed decisions.

Why does treatment sometimes come before a definite diagnosis?

A veterinarian may need to relieve discomfort or stabilize a sick dog while investigating the problem. Some conditions also require a stepwise approach because several diseases produce similar symptoms.

For chronic intestinal problems, a carefully supervised diet trial can be part of the diagnostic process. Improvement on a specific diet provides useful information about the illness. Treatment and investigation sometimes happen together. Current veterinary consensus recognizes treatment response as part of classifying chronic inflammatory enteropathy.

Without reviewing an individual dog’s records, it would be unfair to assume that repeated treatment means a veterinarian is ignoring the cause. But owners deserve to understand the working diagnosis, what remains uncertain, and when the plan should change.

When the same problem returns, ask for a reassessment

Repeated symptoms are a good reason to revisit the plan. Consider asking:

• What conditions could explain this recurring pattern?

• Which possibilities have we ruled out, and how?

• Is this treatment addressing a confirmed diagnosis or providing temporary relief?

• Would my dog’s breed ancestry or family history change your recommendations?

• What should happen if symptoms return after this treatment?

• When would a specialist referral be helpful?

A clear follow-up plan can make the difference between purposeful ongoing care and feeling stuck in a cycle.

DM: where genetic testing helps—and where it has limits

Degenerative myelopathy, or DM, is a progressive neurological disease that typically affects older dogs and can cause worsening hind-leg coordination and weakness. UC Davis lists Golden Retrievers, Bernese Mountain Dogs, and Standard Poodles among breeds with reported clinical disease associated with a SOD1 variant. Crossbred dogs can also be affected. This makes relevant ancestry worth discussing for Goldendoodles and Bernedoodles.

A DNA test can identify a tested DM-associated variant. However, an “at-risk” genetic result does not prove that DM is causing a dog’s current symptoms. Some genetically at-risk dogs never develop the disease. Genetic results need to be interpreted alongside the dog’s age, symptoms, and examination.

UC Davis explains that a clinical diagnosis of DM involves excluding other causes of spinal cord dysfunction. That is why further investigation may still be needed even when genetic testing identifies increased risk.

The useful question is: “Would targeted genetic testing add information to the neurological investigation?”

Why imaging may be part of finding the cause

Imaging is itself a diagnostic tool. Genetic testing identifies particular inherited variants; imaging investigates physical abnormalities. One cannot automatically replace the other.

For example, an unusually firm, enlarged anal sac may need ultrasound or a biopsy to distinguish different conditions. A genetic panel would not answer that question.

Before agreeing to a test, ask: “What are we looking for, and how would the result change treatment?” This helps you understand its purpose and prioritize care with your veterinarian.

Recurring anal gland problems deserve more than a routine assumption

Anal glands, more accurately called anal sacs, can become impacted, inflamed, infected, or abscessed. Repeated scooting should prompt an examination to establish what is actually happening.

For recurring infections, your veterinarian may consider culturing the contents to guide treatment. Dietary fiber may help some dogs by increasing stool bulk and assisting normal emptying. However, an active infection or abscess may require direct treatment.

It is reasonable to ask whether stool consistency, diet, body condition, or another contributing problem deserves attention alongside immediate relief.

Can probiotics help anal glands and gut health?

Selected probiotics may support digestive health and stool quality, with benefits depending on the strain and your dog’s individual needs. Probiotics may be useful for some digestive problems, but benefits depend on the product and the condition being treated.

One controlled study found that a chew containing specific fiber sources and a particular probiotic reduced recurrent anal sac impaction. That is encouraging, but the product contained multiple ingredients: the study does not establish that probiotics alone produced the benefit or that every “anal gland support” supplement works. Dogs needing treatment for underlying skin or gastrointestinal conditions were excluded, which also limits how broadly the findings apply.

Ask your veterinarian which product has relevant evidence, what improvement to expect, and when to reassess if it does not help.

What else can Probiotics help with?

Probiotics may help some dogs with digestive issues, but the benefits depend on the specific strain and the cause of the problem. They are not all interchangeable.

IssueHow probiotics may helpOccasional diarrhea or soft stoolsCertain strains may improve stool consistency or shorten some episodes of diarrhea.Stress-related digestive upsetMay support stool quality during boarding, travel, or other stressful changes.Digestive upset during food changesMay help during a gradual diet transition. They do not replace slowly introducing the new food.

These are common uses described by Cornell’s veterinary resources, although results vary between dogs and products.

Other possible uses need more qualification:

• Chronic intestinal inflammation: Selected probiotics may help alongside a prescribed diet or other treatment. Current veterinary guidance describes the evidence as limited and mixed; probiotics alone are not a reliable treatment for every dog with chronic diarrhea.

• Recurring anal gland impaction: A study found benefits from a supplement combining fiber and a specific probiotic. That does not prove probiotics alone prevent impaction. They do not empty an impacted gland or treat an abscess.

• Some stress-related behaviors: Early research on particular strains suggests possible benefits. This does not mean any general digestive probiotic will treat anxiety.

• If diarrhea keeps returning, lasts more than two days, or comes with vomiting, blood, poor appetite, or lethargy, contact your veterinarian rather than continuing to try supplements. Puppies should be assessed sooner.

Repeated antibiotics deserve a clear explanation

Owners are right to ask why antibiotics are being repeated for chronic digestive symptoms. Current ACVIM-endorsed guidance discourages routine empirical antibiotics for suspected chronic inflammatory enteropathy. It notes that symptoms can recur after antibiotics stop and that these drugs can cause prolonged disruption of intestinal bacteria.

This supports asking whether an antibiotic has a specific indication and whether dietary investigation or additional testing would be more informative. Changes to prescribed treatment should be discussed with the treating veterinarian.

Breed awareness should guide questions

Sharing your dog’s ancestry, family medical history, and available genetic reports can help your veterinarian assess inherited risks. But a breed label cannot explain every case of diarrhea, scooting, or weakness. Likewise, a clear genetic panel only addresses the variants it tests; it is not a guarantee against future illness.

For families raising English Goldendoodles and Bernedoodles, the goal is a collaborative relationship where recurring concerns receive a clear explanation and a plan for further investigation.

You can start that conversation simply: “I want to keep my dog comfortable, and I also want to understand why this keeps returning. Can we make a step-by-step plan to investigate the cause?”

DM is only one example. Knowing a Goldendoodle’s or Bernedoodle’s inherited disease variants can help guide surgical precautions, specialist referrals, monitoring, and sometimes treatment. The value comes from specific health-related variants, rather than breed percentages alone.

These are examples to discuss with a veterinarian—not conditions every doodle is likely to develop:

Inherited condition / Relevant ancestry / How knowing can help with care:

Von Willebrand disease, type 1: Poodles and Bernese Mountain Dogs; relevant to both crosses. This bleeding disorder can change planning for surgery, dental extractions, or injuries. DNA findings can prompt testing of von Willebrand factor levels and preparation for bleeding complications. This is one of the clearest examples of genetics affecting medical precautions.

Progressive retinal atrophy (PRA): Poodle and Golden Retriever lines; different variants occur. Results can guide veterinary eye examinations and help explain progressive vision loss. The benefit is earlier recognition, monitoring, and adapting the home; a DNA result does not provide a cure.

Congenital ichthyosis: Golden Retriever ancestry in Goldendoodles; can help identify an inherited skin-barrier disorder behind persistent scaling. That can direct dermatology care toward ongoing skin management while separately checking for infections or other skin conditions. WITHOUT knowing this genetic issue, some dogs are being with allergy shots that cost over $120 a month, when that NOT going to cure their itchy skin.

Neuronal ceroid lipofuscinosis (NCL): Golden Retriever ancestry; In a dog with compatible progressive neurological signs, testing can help identify a specific inherited disorder and guide neurology consultation, prognosis, and supportive care.

Neonatal encephalopathy with seizures (NEWS): Standard Poodle ancestry and related crosses; Helps explain severe weakness and seizures in very young puppies. Its main benefits are diagnosis, prognosis, and preventing affected litters through informed breeding—not a curative treatment.

UC Davis identifies these inherited disorders and relevant tests; Cornell explains how von Willebrand disease findings inform bleeding assessment and care.

Another important example is Addison’s disease—but it illustrates why ancestry and DNA testing are different: Standard Poodles are predisposed. Addison’s can cause recurring digestive problems, poor appetite, lethargy, or weakness. Knowing that background may encourage a veterinarian to investigate it, but diagnosis requires hormone testing, typically an ACTH stimulation test, rather than a routine genetic health panel. Identifying it can substantially change treatment because the dog needs replacement of deficient hormones.

Inherited risk should be considered when symptoms persist, and relevant genetic reports should be part of the medical record. However:

• A disease-associated variant may indicate risk rather than prove the cause of current symptoms.

• For many recessive conditions, being a carrier does not mean the dog is ill.

• A clear panel only addresses the variants tested.

• Some results change treatment directly; others primarily improve diagnosis, monitoring, or prognosis.

For recurring gut or anal gland problems specifically, there is no single routine DNA panel that reliably identifies the cause. Breed awareness can guide the investigation, while examination, dietary assessment, laboratory testing, and sometimes imaging remain necessary.
