Key Buying Factors
EPA and DHA Levels
We checked the concentration of active fatty acids to ensure each serving provides a therapeutic dose for joint and skin health.
Source of Oil
We prioritized wild caught fish like salmon and pollock to minimize exposure to toxins and ensure a cleaner nutrient profile.
Purity Standards
We verified if brands use third party testing to screen for heavy metals and ensure the oil meets safety specifications.
Form and Delivery
We evaluated the difference between liquid pumps, soft gels, and chews to see which is easiest to administer to dogs.
Freshness Indicators
We looked for antioxidants like Vitamin E and packaging that protects the oil from oxidation to prevent rancidity.
Palatability
We analyzed owner feedback regarding smell and taste to determine if dogs typically accept the supplement without fuss.
Care, Cost and Maintenance
Storage
Keep fish oil in a cool, dark place or refrigerate after opening to maintain freshness and prevent spoilage.
Gradual Introduction
Start with half the recommended dose and slowly increase over a week to allow your dog's digestive system to adjust.
Regular Inspection
Check the oil for a rancid smell or change in color before each use, as oxidized oil can be harmful.
If your dog refuses to eat the oil, try freezing it into an ice cube tray with a little low sodium broth. We discovered this trick works well to mask the fish scent while the dog enjoys a cold treat.
