A veterinary nutritionist can help ensure your dog gets all the nutrients she needs to fuel her body during cancer treatment – and beyond.
What Is a Veterinary Nutritionist?
Veterinary nutritionists are veterinarians with advanced training and experience in nutrition. Dogs have specific nutritional requirements that differ from those of humans and other animals. They also have distinct needs for various life stages (growth, adult, and reproduction) and activity levels (from couch potato to sled dog in the Iditarod), as well as for disease processes.
Nutritionists study dietary requirements and how to apply them to nourish patients properly. Veterinary nutritionists can formulate a diet for home cooking for your individual pet or provide guidance on choosing a commercially prepared diet that will best meet your dog’s unique needs. They also work on a larger scale, designing diets for commercial dog food production.
Board-certified veterinary nutritionists
Board-certified veterinary nutritionists are licensed veterinarians that have undertaken at least two years of additional training in nutrition, involving clinical work, research, and teaching.
To become “boarded” as a Diplomate in the American College of Veterinary Nutrition, veterinarians submit detailed case reports, publish peer-reviewed research, and pass a two-day rigorous written exam.1
Animal nutritionists may have a bachelor’s or master’s degree or Ph.D. in animal nutrition, or they may hold nutrition certifications from various organizations. Many universities offer degree programs in animal nutrition, while others feature nutrition concentrations as part of related fields of study.2
The Role of Nutritionists in Pet Food Companies
Reputable pet food companies employ nutritionists to formulate their recipes. Nutritionists evaluate raw ingredients, results of finished product nutritional analysis, and product labeling, so they are essential for the manufacture of safe and nutritious pet foods. PhD animal nutritionists also have extensive training in the science of processed food manufacturing and its impact on nutrients.
By employing nutritionists, companies ensure their diets meet AAFCO standards (US) or FEDIAF standards (Europe) for species and life stage. That means the diets provide nutrients that are above the minimum requirements to maintain health and function, while not exceeding maximum limits that could cause dietary toxicities.
Role of Nutritionists for Homemade Diets
Feeding a homemade diet is not just a matter of offering wholesome, dog-safe foods; although that is a key component, those foods must be fed in carefully selected proportions for optimal nutrition. Feeding your dog any diet that is not complete and balanced can do more harm than good over time.
Board-certified nutritionists play a critical role in formulating homemade diets (creating the recipes) to ensure they are complete and balanced. The recipe must be followed exactly, with no substitutions in ingredients or changes in measurements. Any modification could shift the nutrient balance out of the required range.
Does My Dog Need a Nutritionist?
Often, dog lovers begin to evaluate their dog’s diet, lifestyle, and environment after a cancer diagnosis in an effort to improve overall health.3 This often prompts us to make changes, and many people value the input of knowledgeable experts to guide them. A nutritionist might be an important member of your team if your dog has cancer. A nutritionist is often critical if your dog also has other health conditions that require special diets.
Nutritionists Can Help with Cancer Diets
Your dog’s diet may have a direct effect on cancer. For example, selenium, the omega-3 fatty acids DHA and EPA, and arginine are nutrients that may exert anti-cancer effects against certain tumor types.
In addition, DHA, EPA, arginine, and branched chain amino acids may help combat cachexia, allowing dogs with cancer to maintain healthy body weight.4
Veterinary nutritionists can formulate diets that include therapeutic levels of these nutrients – from whole food sources or from supplements – without negatively impacting overall dietary balance.
Nutritionists Can Help with Side Effect Management
You may also consider a nutritionist to help manage potential side effects of cancer treatment. For example:
Vomiting and diarrhea may be eased by a bland diet.
Decreased appetite and the resulting fat and muscle loss might be shifted through the use of calorie-and nutrient-dense diets.
A high-fiber diet could help relieve medication-induced constipation.
Nutritionists Can Help with Special Needs Diets
Besides recommending helpful additions to diet, nutritionists provide guidance on foods to avoid. For example, some dogs with mast cell tumors may benefit from reducing histamine in their diet, so nutritionists can formulate low-histamine recipes.
Nutritionists Can Help with Raw Diet Considerations
Most veterinarians recommend avoiding raw diets for dogs undergoing chemotherapy or radiation] because immunosuppression can make them vulnerable to pathogens – bacteria, viruses, and other microorganisms that can cause infection.
But simply cooking the food you used to serve raw may throw the balance of nutrients off. Cooking your dog’s food can reduce the presence of potential pathogens, but it also reduces the amount of some nutrients, notably the vitamins thiamine and choline. Veterinary nutritionists can advise whether modifications need to be made to the cooked recipe to meet nutrient requirements.
Nutritionists Can Help with Non-Standard and Complex Diets
Therapeutic diets that contain nutrient concentrations outside of typical healthy dog diets – like ketogenic diets, or diets with higher-than-standard vitamins or minerals – are best formulated and monitored by board-certified nutritionists.
And if your dog has multiple health challenges, nutritionists can manage the intricacies of a diet plan that takes all your dog’s needs into account.
