Nova Scotia Duck Tolling Retriever Nutrition & Longevity Guide — Immune Health and Joint Support

Do you ever watch your Toller's tail wag with such enthusiasm it seems their whole body is wiggling? Or marvel at that stunning red-gold coat? The Nova Scotia Duck Tolling Retriever, or Toller, is Canada's smallest retriever breed and truly one of its best-kept secrets. Weighing 17-23 kg, these incredible dogs were developed in Nova Scotia to lure and retrieve waterfowl. Their unique "tolling" behavior—playful movements at the water's edge that attract curious ducks within shooting range—demands intelligence, endurance, and an intense love of water. We know how much you adore your Toller, and because they're family, we want you to be aware that beneath that athletic exterior, Tollers can sometimes face immune-mediated diseases. Understanding these conditions helps us make the best nutritional choices for them, and we're here to help guide you.

SRMA: The Breed's Signature Immune Challenge

Steroid-responsive meningitis-arteritis (SRMA) is an immune-mediated inflammatory condition that affects the meninges (the membranes surrounding the brain and spinal cord) and blood vessels. It’s something many Toller owners become familiar with, as Nova Scotia Duck Tolling Retrievers have one of the highest breed incidences of SRMA in the world. This condition typically strikes young dogs between 6 and 18 months of age, though it can occur at any age.

Symptoms include severe neck pain and stiffness, fever, reluctance to move, and a characteristic "prayer position" where your dog stretches with front legs extended and head low. It's a worrying sight, and without treatment, SRMA can cause permanent neurological damage.

Treatment involves high-dose corticosteroids (typically prednisolone) tapered over months. This is where nutrition really matters, and we want to make sure you have the best information:

• Corticosteroid side effects: Long-term steroid use causes increased appetite, water retention, muscle wasting, and immune suppression. We know how tempting it is to give in to those hungry eyes, but calorie control becomes essential—a Toller on prednisolone will act ravenous and can gain weight rapidly if fed freely.
• Increased protein needs: Steroids cause protein catabolism (muscle breakdown). To help counteract muscle loss, feed higher protein (28-32% on dry matter basis) from high-quality animal sources.
• Omega-3 fatty acids: EPA and DHA have anti-inflammatory properties that may complement steroid therapy. Fish oil supplementation (1,000-1,500 mg EPA+DHA daily for an adult Toller) is commonly recommended by veterinary neurologists managing SRMA, and it's a step we often see make a difference.
• Gut health: Steroids and antibiotics used in SRMA treatment disrupt the gut microbiome. Probiotics (Saccharomyces boulardii or canine-specific Lactobacillus strains) can support digestive function during treatment, helping your Toller feel better from the inside out.
• Bone health: Long-term corticosteroids reduce bone density. Ensure adequate calcium and vitamin D in the diet, and consider joint supplements to keep them strong.

Addison's Disease: When the Adrenals Fail

Another condition we often see in Tollers is Hypoadrenocorticism, more commonly known as Addison's disease. This happens when the adrenal glands fail to produce adequate cortisol and aldosterone. Tollers are predisposed to the immune-mediated form, where their own immune system unfortunately destroys the adrenal cortex. This really highlights the breed's broader pattern of immune dysregulation, and it's why we care so much about proactive care.

Addison's is often called "the great pretender" because symptoms can be vague and episodic—things like lethargy, vomiting, diarrhea, weight loss, weakness, and even collapse. It can be hard to pinpoint, which is why staying observant is key. An Addisonian crisis (acute adrenal failure) is a life-threatening emergency characterized by shock, severe dehydration, and dangerously high potassium levels, so knowing the signs is really important.

Nutritional management for a Toller with Addison's disease:

• Consistent feeding schedule: Addisonian dogs truly thrive on predictable routines. Feeding at the same times daily helps maintain stable blood glucose and electrolyte levels, giving them a sense of security and stability.
• Sodium considerations: Dogs on mineralocorticoid replacement (fludrocortisone or DOCP) typically maintain normal sodium balance. However, during illness or stress, sodium losses can increase. We want to be clear: Do not restrict sodium unless specifically directed by your veterinarian.
• Easily digestible food: Addisonian dogs often have reduced appetite and sensitive digestion during flares. Having a highly palatable, easily digestible food ready for these times—like boiled chicken and rice, or a veterinary gastrointestinal diet—can make a huge difference.
• Stress management: While not strictly nutritional, we know that physical and emotional stress can trigger Addisonian crises. Keeping feeding environments calm and avoiding sudden dietary changes that could cause gastrointestinal upset are simple ways to show you care.

Hip Dysplasia and Joint Support

Your Toller's boundless energy and love for activity mean their joints work hard! As a medium-sized retriever bred for athletic work, the Toller is subject to hip dysplasia, though at lower rates than larger retriever breeds. The OFA reports that approximately 8-10% of evaluated Tollers show some degree of hip dysplasia. For a breed expected to swim, run, and retrieve for hours, even mild hip issues can significantly impact their quality of life, and we want to help keep them comfortable and active alongside you.

We recommend starting joint supplements from young adulthood (age 1-2), especially for Tollers that are actively working, competing in dock diving, agility, or field trials. It's a proactive step that can make a real difference. Don't wait for lameness to appear—by that point, significant cartilage damage has already occurred, and we want to help prevent that.

The Water Retriever's Unique Joint Demands

Tollers are water dogs through and through, and we know how much they love to splash! Swimming is excellent low-impact exercise for joint health, but the cold water they often work in can temporarily stiffen joints. After those invigorating cold-water sessions, allow a gradual warm-up period rather than immediately transitioning to high-impact land activities. Adequate omega-3 intake supports joint flexibility and reduces post-exercise inflammation, helping them stay ready for their next adventure.

Fueling the High-Energy Athlete

If you own a Toller, you know they're not typically couch potatoes! They have a medium-to-high energy level that reflects their working heritage, and they are truly at their best when they have a job to do. We know what works to keep them fueled, and their caloric needs scale significantly with activity level:

For your actively working Toller, the timing of meals really matters. We suggest avoiding a large meal within 2 hours of intense exercise—instead, feed a small snack 1-2 hours before activity and the main meal after cool-down. For competition days, bringing easily digestible high-value treats (like chicken breast or liver) for energy between sessions is a great strategy, rather than relying on a single large meal.

Progressive Retinal Atrophy and Eye Health

As owners, we want to protect our Toller's sight. Tollers are affected by progressive retinal atrophy (PRA), specifically the prcd-PRA form. This genetic condition causes gradual degeneration of photoreceptor cells in the retina, leading to night blindness progressing to complete blindness. Genetic testing is available and should be performed before breeding, and it's a responsible step we encourage.

While no diet can prevent or cure PRA, antioxidant-rich nutrition supports retinal health and may slow progression:

• Lutein and zeaxanthin: These concentrate in the retina and provide photoprotection. You'll find them in eggs, leafy greens, and some premium dog foods.
• DHA omega-3: A structural component of retinal cell membranes. Fish oil supplementation supports retinal membrane integrity, which is a simple way to show support.
• Vitamin E and selenium: These work to protect retinal cells from oxidative damage, keeping those precious eyes healthier.
• Vitamin A: Essential for rod cell function (night vision). Most commercial diets provide adequate levels, but dogs with PRA may benefit from ensuring optimal intake, and we can help you explore options.

Coat Health and the Tolling Double Coat

That gorgeous, water-repellent double coat is one of your Toller's most striking features, isn't it? The outer coat has a slight wave, and the undercoat is soft and dense. We know you want to keep it looking its best, and maintaining this coat in top condition truly requires the right nutritional support:

• Omega-3 and omega-6 balance: A ratio of omega-6 to omega-3 between 5:1 and 10:1 supports coat health and natural water repellency. Fish oil supplementation tilts this ratio favorably, helping that coat shine.
• Biotin: This nutrient supports coat quality and skin health. Most premium dog foods include adequate biotin, but supplements are available for dogs with dull or brittle coats if you feel they need an extra boost.
• Zinc: Deficiency causes dull coat, hair loss, and skin lesions. Make sure the food contains zinc in a bioavailable form (zinc methionine or zinc proteinate rather than zinc oxide) to keep their skin and fur happy.
• Protein quality: Hair is primarily keratin, a protein. So, adequate high-quality animal protein intake is truly the foundation of a healthy, beautiful coat.
