Understanding Canine Gut Health: What We Learned at the Dog Gut Health Summit
Insights from Dr. Ava Frick’s presentation, “Causes of Bad Digestion and Why Your Dog May Be Prone to GI Upset”
At Vom Geliebten Haus, we believe responsible breeding involves much more than carefully selecting pedigrees and raising beautiful German Shepherd puppies. It requires a lifelong commitment to understanding canine health, nutrition, behavior, and overall well-being.
Continuing education is an important part of that commitment. In October 2026, we attended the Dog Gut Health Summit, where veterinary professionals and canine health specialists shared their knowledge about digestive health and the many factors that influence it.
One particularly interesting presentation featured Dr. Ava Frick, a veterinarian with more than 40 years of experience and additional training in animal chiropractic, herbal therapy, whole-food nutrition, and microcurrent therapy.
Her presentation, “Causes of Bad Digestion and Why Your Dog May Be Prone to GI Upset,” explored an important concept: digestive problems are not always simply about what a dog eats. The nervous system, stress, environment, nutrition, and other aspects of health can all influence gastrointestinal function.
Here are some of the key topics discussed and the lessons we took away from this presentation.
1. The Connection Between Stress and Digestion
One of the central themes of Dr. Frick’s presentation was the relationship between the nervous system and digestive health.
The autonomic nervous system regulates many functions that happen automatically, including heart rate, breathing, intestinal movement, and aspects of digestion.
Three important components were discussed:
Sympathetic nervous system: Commonly associated with the “fight-or-flight” response. It prepares the body to respond to stressful or threatening situations.
Parasympathetic nervous system: Often described as the “rest-and-digest” system. It supports digestive activity, recovery, and normal bodily maintenance.
Enteric nervous system: A complex network of nerves within the gastrointestinal tract that helps coordinate digestion and intestinal movement.
Dr. Frick explained that when a dog experiences stress, the sympathetic nervous system becomes more active. During an acute stress response, the body prioritizes immediate survival rather than digestion.
Stress can influence gastrointestinal motility, appetite, intestinal sensitivity, and digestive function. In some dogs, stressful situations may contribute to vomiting, loose stools, reduced appetite, or changes in bowel movements.
However, digestive symptoms can have many causes, including infections, parasites, dietary intolerances, inflammatory conditions, and other illnesses. Stress should be considered as one possible contributing factor rather than assumed to be the cause.
Our Takeaway
A dog's emotional well-being deserves attention alongside physical health.
At Vom Geliebten Haus, we place great importance on raising puppies in a family environment, providing positive early experiences, and helping them develop confidence.
Understanding the relationship between stress and digestion reinforces why thoughtful socialization, predictable routines, and positive handling are so important.
2. Some Dogs Show Stress Differently Than Others
Not every stressed dog behaves the same way.
During the presentation, Dr. Frick discussed dogs that demonstrate obvious signs of stress, including nervousness, excessive excitement, fearfulness, and difficulty settling down.
She also described dogs that may experience stress without displaying dramatic outward behaviors.
Some dogs become restless, vocal, or destructive. Others may become unusually quiet, withdrawn, or hesitant.
Possible behavioral signs of stress include:
Difficulty relaxing after excitement
Changes in appetite or eating habits
Excessive pacing, whining, or restlessness
Increased sensitivity to sounds or environmental changes
Changes in sleeping patterns
Stress-related changes in stool consistency
These behaviors are not specific to stress, and persistent changes should always be evaluated appropriately.
Our Takeaway
Temperament is more than whether a dog appears friendly or active.
A stable nervous system, the ability to recover from excitement, and confidence in everyday situations are qualities we value in our German Shepherd breeding program.
We also recognize that puppies have individual personalities. Understanding those differences helps us make thoughtful temperament-based placements with families whose lifestyles and expectations are compatible with each puppy.
3. Why Consistent Routines Matter
Another interesting discussion focused on the importance of predictability in a dog's environment.
Dr. Frick explained that dogs often benefit from knowing what to expect throughout their day.
Feeding schedules, opportunities for rest, exercise, interaction, and familiar household routines can provide a sense of security.
This does not mean every day must be identical. Dogs can learn to adapt to changing schedules and new experiences.
However, a constantly unpredictable environment, particularly for a sensitive dog, may contribute to stress.
Our Takeaway
We believe puppies benefit from a balance of structure and appropriate new experiences.
Our puppies are raised indoors, where they become familiar with household activity, human interaction, everyday sounds, and family routines.
As they mature, we encourage their new families to establish consistent expectations while gradually introducing new environments and experiences.
A confident German Shepherd should learn not only how to explore the world but also how to relax within it.
4. Hair Tissue Mineral Analysis: An Integrative Perspective
One of the more specialized topics in Dr. Frick's presentation was hair tissue mineral analysis.
She described this laboratory procedure as a way to measure mineral concentrations and certain metals present in hair samples.
According to Dr. Frick, she uses these results as part of her individualized approach to nutritional assessment.
The minerals discussed included calcium, magnesium, sodium, potassium, zinc, selenium, iron, and other elements involved in normal physiological functions.
She also described using patterns in these measurements to evaluate what she considers metabolic and stress-related imbalances.
What Is Important to Understand
Although hair analysis can measure certain substances, its use for diagnosing nutritional deficiencies, thyroid or adrenal dysfunction, stress levels, or specific dietary requirements in dogs is not well validated.
Hair mineral concentrations can be affected by environmental contamination, grooming products, coat characteristics, and laboratory methods.
For suspected nutritional deficiencies or endocrine disorders, veterinarians generally rely on clinical examinations, dietary histories, and appropriate validated diagnostic testing.
Our Takeaway
The most valuable principle from this discussion was the importance of individualized care.
Every dog has a unique health history, activity level, metabolism, and nutritional needs.
Rather than assuming that one supplement or feeding approach is appropriate for every dog, we believe nutritional decisions should be informed by the individual animal and reliable veterinary evidence.
5. Environmental Exposures and Heavy Metals
Dr. Frick also discussed environmental substances that may affect animal health.
Her presentation included potential exposure to aluminum, lead, mercury, pesticides, herbicides, and chemicals associated with certain building materials.
Dogs can encounter environmental contaminants through drinking water, food, soil, household materials, and other sources.
Some heavy metals are harmful when exposure reaches toxic levels. For example, lead poisoning can cause neurological and gastrointestinal symptoms, while significant mercury exposure can affect the nervous system and other organs.
Dr. Frick discussed hair analysis as a way of investigating these exposures. However, suspected heavy-metal poisoning requires veterinary assessment and appropriate testing; hair analysis alone cannot establish toxicity.
Our Takeaway
Environmental safety is an important part of responsible animal care.
We believe it is worthwhile to pay attention to drinking water quality, safe food storage, household cleaning products, outdoor chemicals, and materials accessible to dogs.
Puppies are naturally curious and explore their surroundings with their mouths, making a carefully maintained environment particularly important.
6. The Role of Nutrition in Gut Health
Nutrition was one of the strongest recurring themes throughout the presentation.
Dr. Frick encouraged pet owners to consider the quality and variety of foods offered to their dogs.
She expressed a preference for fresh, minimally processed foods and discussed home-cooked and raw diets as alternatives or additions to commercial kibble.
Her broader message was that feeding should support the whole animal rather than simply satisfy hunger.
What Does Research Tell Us?
Dogs require a nutritionally complete and balanced diet containing appropriate amounts of protein, fat, essential fatty acids, vitamins, and minerals.
Well-formulated commercial diets can meet these needs, as can properly formulated home-prepared diets.
Fresh ingredients may provide variety and enrichment, but a homemade diet must be carefully balanced if it replaces a dog's primary food.
Raw diets require additional consideration because they can expose dogs and people to harmful bacteria. This is particularly important in households with young puppies, children, or vulnerable individuals.
Our Takeaway
Nutrition is a foundation of lifelong canine health.
We believe in carefully evaluating the foods we provide and recognizing that a dog's nutritional needs change throughout life.
Growing puppies, active adults, breeding females, and senior dogs do not necessarily have identical nutritional requirements.
We also recognize that food transitions should be gradual, particularly for puppies moving into new homes.
7. Dietary Variety and the Gut Microbiome
One of the most memorable discussions concerned the intestinal microbiome.
The gut microbiome consists of microorganisms, including bacteria, that inhabit the digestive tract.
These microorganisms contribute to important functions such as nutrient metabolism, intestinal health, and communication with the immune system.
Dr. Frick emphasized dietary variety and suggested that feeding the same ingredients continuously may limit microbial diversity.
Research indicates that diet can influence the composition and activity of the canine gut microbiome. However, greater dietary variety does not automatically mean better health, and microbial diversity alone is not a complete measure of gut health.
Some dogs tolerate dietary changes easily, while others require consistent diets because of allergies, gastrointestinal disease, or individual sensitivities.
Our Takeaway
Supporting a healthy microbiome is an important part of canine nutrition.
We believe that dietary choices should consider digestive tolerance, nutritional completeness, and the individual dog's response.
For puppies, especially during the transition into a new home, consistency is particularly valuable.
We recommend maintaining their familiar diet initially and introducing any changes gradually to reduce the likelihood of digestive upset.
8. Thyroid Function and Nutritional Balance
Dr. Frick discussed the relationship between thyroid hormones and essential nutrients, including iodine and selenium.
Both nutrients play important roles in thyroid physiology.
Iodine is required for thyroid hormone production, while selenium is involved in enzymes that help regulate thyroid hormone metabolism.
She also discussed her interpretation of hair mineral analysis in evaluating thyroid-related concerns.
It is important to distinguish these ideas from established diagnostic practices.
Hair mineral analysis cannot reliably diagnose hypothyroidism, and dogs with confirmed hypothyroidism generally require appropriate veterinary treatment, often including thyroid hormone replacement.
Our Takeaway
Normal endocrine function is essential to overall health, including metabolism, growth, energy regulation, and many other physiological processes.
Balanced nutrition helps provide the nutrients required for these systems to function properly.
When hormonal disease is suspected, accurate diagnosis and individualized veterinary care are especially important.
9. Early Spaying and Neutering: Considering Long-Term Development
Another topic that stood out to us was Dr. Frick's discussion of early spaying and neutering.
She emphasized the role of reproductive hormones in physical development, including skeletal maturation.
Sex hormones influence growth plate closure, and removing the reproductive organs before skeletal maturity can alter aspects of normal development.
Research has identified associations between the timing of sterilization and certain orthopedic disorders in some breeds, including German Shepherds.
However, risks and benefits vary according to breed, sex, age, health, and individual circumstances.
Dr. Frick also discussed glandular supplements derived from reproductive tissues. These products have not been demonstrated to reliably replace the physiological effects of normal reproductive hormones.
Our Takeaway
This topic is particularly relevant to our breeding philosophy.
At Vom Geliebten Haus, we recommend delaying routine spaying or neutering until at least 24 months of age, unless an individual dog's medical circumstances warrant a different approach.
We believe allowing German Shepherds adequate time for physical development is an important consideration.
We encourage every family to discuss the timing of sterilization with their veterinarian, taking into account the dog's health, lifestyle, and individual risk factors.
10. Looking at the Whole Dog
Perhaps the most valuable message of Dr. Frick's presentation was the importance of considering the dog as a complete individual.
Digestion does not happen independently of the rest of the body.
The gastrointestinal system communicates with the nervous system, endocrine system, and immune system. Nutrition, environmental conditions, activity, illness, and stress can all influence digestive health.
A dog experiencing recurrent gastrointestinal symptoms may need more than a simple food change.
Identifying the underlying cause can involve examining diet, parasite exposure, medical history, environmental changes, stressors, and other health conditions.
Our Takeaway
We believe responsible dog ownership requires observation, education, and a willingness to investigate changes rather than simply treating recurring symptoms.
Whether we are raising young puppies or caring for our adult German Shepherds, we strive to consider their physical health, temperament, nutrition, and environment together.
Final Thoughts: Continuing Education Makes Us Better Breeders
Attending the Dog Gut Health Summit provided another opportunity to explore the complex relationship between nutrition, behavior, environment, and digestive function.
Dr. Ava Frick's presentation encouraged us to think about how different systems of the body interact and how individual dogs may respond differently to similar circumstances.
While some approaches discussed during the seminar remain experimental or lack sufficient scientific validation, the presentation reinforced several important principles that align with our breeding philosophy:
Emotional well-being and physical health are interconnected.
Predictable routines and positive experiences can support a dog's ability to cope with stress.
Balanced nutrition is essential throughout every stage of life.
Gut health involves much more than simply choosing a particular brand or type of food.
Supplements and dietary changes should be selected thoughtfully.
Large-breed development deserves special consideration when making decisions about sterilization.
Every dog deserves individualized care based on its temperament, health, and needs.
At Vom Geliebten Haus, our commitment to our German Shepherds does not end with health testing, selecting pedigrees, or raising puppies.
We believe continuing education helps us ask better questions, evaluate new information, and make thoughtful decisions for the dogs entrusted to our care.
Our goal remains the same: to raise healthy, confident, well-socialized long-coat German Shepherds and provide their future families with the knowledge and support needed for a lifetime of responsible ownership.
