Living With It
Care, Cost and Maintenance
Storage
Keep omega-3 supplements in a cool, dry place. Refrigerate after opening if recommended to prevent rancidity.
Dosing
Follow label instructions based on your dog's weight. Start with a lower dose and increase gradually to avoid digestive upset.
Monitoring
Watch for improved coat shine, reduced shedding, or less itching. Give it at least 4-6 weeks to see results.
Pro tip
We recommend rotating between different omega-3 sources (like salmon and pollock) to provide a broader range of fatty acids and reduce the risk of heavy metal buildup.
Frequently asked questions
Can I give my dog human omega-3 supplements?
We advise against it. Human supplements may contain ingredients toxic to dogs like xylitol or have different concentrations. Always choose a product formulated for dogs.
How long until I see results from omega-3s?
Most owners see improvements in coat and skin within 4 to 8 weeks. For joint benefits, it may take up to 12 weeks.
What is the difference between EPA and DHA?
EPA primarily supports skin, coat, and anti-inflammatory responses, while DHA is key for brain and eye development. Both are beneficial.
Can omega-3s help with my dog's allergies?
Yes, omega-3s can reduce inflammation associated with allergies, but they are not a cure. We recommend using them alongside other treatments as directed by your vet.
Are there side effects of omega-3 supplements?
Some dogs may experience mild digestive upset like diarrhea or fishy breath. Start with a low dose and increase gradually to minimize these effects.
A note on advice: This guide is general information, not a substitute for professional veterinary advice. Talk to your vet before changing your dog's diet or care routine, especially if your dog has allergies, kidney disease, pancreatitis, obesity, heart disease or any other medical condition.
