What to do
Start with a small amount and increase gradually.
When to contact a vet: Contact a vet if symptoms persist.
Symptoms to look for

Why
Flaxseed is a source of fibre and omega-3 fatty acids. It should be ground for best absorption. Whole flaxseeds may pass through the gut unchanged. Store ground flaxseed in the fridge to prevent rancidity.

Dogs can react differently depending on their size, age, health, allergies, medications, the amount consumed and other circumstances. An item classified as Safe is not necessarily suitable for every individual dog.
If your dog has eaten something potentially poisonous or dangerous, has eaten an unknown substance, or is showing concerning symptoms, contact your veterinarian or an emergency veterinary service immediately.
Do not induce vomiting or give your dog medication unless specifically instructed to do so by a veterinary professional.
