Your dog has osteoarthritis – and you’re doing your best with walks, massages and perhaps even physiotherapy. But have you ever taken a look in their food bowl? What your dog eats every day affects their joints more than you realise. The wrong diet can promote inflammation and make the osteoarthritis worse. The right one can relieve pain.
Key points at a glance
- Certain foods promote inflammation and worsen osteoarthritis
- Omega-3 fatty acids and anti-inflammatory ingredients can reduce joint pain
- A proper diet is no substitute for dietary supplements, but it lays the foundation
- Small changes to your dog’s diet often show results after just 4–6 weeks
These 5 foods make your dog’s osteoarthritis worse
Before we talk about what helps – let’s talk about what harms. Many dog owners unwittingly feed their dogs things that fuel inflammation in the body.
1. Large quantities of grains
Wheat, maize and soya contain lectins and omega-6 fatty acids. In large quantities, they upset the balance between omega-6 and omega-3 – and that promotes inflammation. Many budget dry foods consist of 40–60 per cent grains. Your dog with osteoarthritis doesn’t need that.
What you can do: Check the ingredients list. Are grains listed right at the top? If so, they’re the main ingredient. Switch to a grain-free or low-grain food.
2. Sugar and hidden sweeteners
Sugar may seem obvious – but it’s hidden in many treats and wet foods. Caramel, molasses, beet pulp – they’re all sources of sugar. Sugar promotes inflammation and contributes to weight gain. And every extra kilo puts additional strain on joints that are already damaged.
3. Cheap fats and vegetable oils
Sunflower oil, maize oil, soya oil – these oils are full of omega-6 fatty acids. Your dog needs an omega-6 to omega-3 ratio of no more than 5:1. Many dog foods have a ratio of 20:1 or worse. This is a trigger for inflammation.
4. Processed meat and offal
‘Animal by-products’ on the label can mean anything – from lungs to feathers to hooves. Low-quality protein sources put a strain on the metabolism and provide hardly any of the amino acids your dog needs for joint development.
5. Nightshade vegetables
Tomatoes, peppers and potatoes contain solanine. In large quantities, solanine can exacerbate inflammation. For dogs with osteoarthritis, it’s worth reducing potato-based food and switching to sweet potato.
What really helps your dog with osteoarthritis
Now for the good news: with the right diet, you can actively combat the inflammation.
Omega-3 fatty acids – the most important building block
Omega-3 fatty acids (EPA and DHA) have anti-inflammatory effects. The best sources for your dog:
- Salmon and sardines: Rich in EPA and DHA. A small portion of fresh or frozen fish (not smoked salmon) 2–3 times a week
- Salmon oil or fish oil: 1 teaspoon per 10 kg of body weight, added to their food daily
- Green-lipped mussel: Contains a special form of omega-3 (ETA) which also has anti-inflammatory properties. This is why green-lipped mussel from New Zealand is also a key ingredient in Veddelholzer Joint Tablets
Turmeric – the natural anti-inflammatory
Turmeric contains curcumin, a powerful anti-inflammatory compound. Important: Curcumin is poorly absorbed by the body. Always mix it with a pinch of black pepper (piperine) and a little coconut oil – this increases absorption many times over.
Dosage: A pinch of turmeric per 10 kg of body weight, once a day mixed with food.
Bone broth – joint nutrition from the kitchen
Homemade bone broth is a natural source of collagen, glucosamine and chondroitin – exactly the substances your dog needs for its joint cartilage.
Here’s how to make bone broth: Cover beef or chicken bones with water, add a dash of apple cider vinegar (to leach the minerals from the bones), and simmer on a low heat for 12–24 hours. Strain, leave to cool, then freeze in portions.
Blueberries and dark leafy vegetables
Blueberries are rich in antioxidants that combat free radicals and reduce inflammation. Spinach and kale provide vitamin K and manganese – important for bone metabolism. A handful of blueberries or puréed leafy greens mixed into their food – that’s it.
Ginger – the insider tip
Fresh ginger has anti-inflammatory and pain-relieving properties. Finely grate a small slice (approx. 1 cm per 10 kg of body weight) and mix it into their food. Don’t overdo it – too much can irritate the stomach.
BARF for osteoarthritis – yes or no?
Many dog owners with dogs suffering from osteoarthritis are considering switching to BARF (Biologically Appropriate Raw Food). This can be a good idea – but only if you do it properly.
Benefits for osteoarthritis:
- You control every ingredient
- No hidden grains, no sugar
- Fresh sources of omega-3 (fish, salmon oil)
- Bone broth as a base
Risks:
- Without the right knowledge, important nutrients can quickly be missing
- The calcium-phosphorus ratio must be correct
- Malnutrition is particularly problematic for dogs with osteoarthritis
Recommendation: If you want to feed your dog a BARF diet, get a personalised plan drawn up by a canine nutritionist. The investment (approx. 80–150 euros, one-off) is well worth it.
Diet alone is not enough – but it is the foundation
Even the best diet cannot magically restore damaged cartilage. But it can reduce inflammation, protect the remaining cartilage and significantly improve your dog’s well-being.
For targeted joint support, your dog often needs more than standard dog food can provide. The best way to ensure they receive glucosamine, chondroitin, MSM and hyaluronic acid in therapeutic doses is through a high-quality dietary supplement. Veddelholzer Joint Tablets combine precisely these ingredients with green-lipped mussel, devil’s claw and ginger – and taste like treats to most dogs. The right diet plus targeted supplementation – that’s the combination that really makes a difference.
Feeding plan: This is what a joint-friendly day looks like
Morning:
- High-quality, grain-free wet food or a BARF portion
- 1 tsp salmon oil
- A pinch of turmeric with a dash of pepper
Evening:
- Second main meal
- Pureed leafy vegetables or a few blueberries
- A joint supplement tablet as a treat
In between meals:
- Bone broth as a snack (lukewarm)
- No sugary treats
Frequently asked questions
What is the best food for dogs with osteoarthritis?
A grain-free or low-grain food with a high meat content and added fish oil (omega-3). Check the ingredients list: meat should be listed first, with no grains or sugar in the top five.
Can my dog with osteoarthritis eat rice?
In small quantities, yes. Rice is easily digestible and contains fewer pro-inflammatory substances than wheat. But it shouldn’t make up the bulk of the meal. Better options: sweet potato or pumpkin as a source of carbohydrates.
How long does it take for the change in diet to take effect?
Allow 4–6 weeks. Inflammatory processes in the body take time to change. Consistency is key – don’t feed your dog one way one day and another the next. Some owners report initial improvements after just 2 weeks.
Can I give my dog turmeric every day?
Yes, in the correct dosage (a pinch per 10 kg), turmeric is safe to give daily. Always give it with a pinch of black pepper and a little fat, otherwise the body will hardly absorb the curcumin.
Should I switch to a grain-free diet for my dog’s osteoarthritis?
It is recommended. Large quantities of grains can promote inflammation. A grain-free diet with good sources of fat and a high protein content is the better choice for dogs with osteoarthritis.
Are dietary supplements really necessary for osteoarthritis?
The right diet is the foundation – but it usually does not provide enough glucosamine, chondroitin or MSM in therapeutic amounts. Targeted supplementation bridges this gap and provides additional support for the joint cartilage.
When should you see a vet?
Dietary changes and supplements are no substitute for veterinary treatment. Take your dog to the vet if:
- Your dog suddenly starts limping severely or can no longer put any weight on a leg
- The joints are visibly swollen, hot or red
- Your dog shows no improvement after 8 weeks despite dietary changes and supplementation
- He refuses to eat or is losing a lot of weight
- You notice a fever or lethargy – these can be signs of an infection
Your vet can take X-rays, assess the severity of the osteoarthritis and, if necessary, prescribe painkillers. The right diet and supplements complement veterinary treatment – they do not replace it.
