Check for essential vitamins (A, D, E, B12), minerals (zinc, selenium), and added benefits like probiotics or joint support.
04

Care, Cost and Maintenance
Dosage Precision
Always measure the exact amount recommended for your dog's weight. Using a kitchen scale for chews or a syringe for liquids helps avoid over- or under-dosing.
Storage
Store vitamins in a cool, dry place away from sunlight. Some liquids require refrigeration after opening-check the label.
Monitor Stool and Behavior
When introducing a new supplement, watch for any changes in digestion, energy, or coat quality. If problems arise, discontinue and consult your vet.
Pro tip
We recommend rotating between a high-calorie supplement for underweight dogs and a comprehensive multivitamin for maintenance. Always introduce one product at a time to monitor your dog's tolerance.
Frequently asked questions
Are dog vitamins necessary for small breeds?
Not always, but they can help fill nutritional gaps in home-cooked or low-quality diets. A balanced commercial diet usually meets all needs.
Can I give human vitamins to my dog?
No, human vitamins may contain toxic ingredients like xylitol or excessive doses. Always use products formulated for dogs.
What is the best form of vitamin for picky dogs?
Liquid drops can be hidden in food, while soft chews are often more palatable. We found liquid to be most versatile for small, picky dogs.
How quickly can I see results from dog vitamins?
Improvements in coat and energy may be visible within 2-4 weeks, but some benefits like joint support may take longer.
Should I consult my vet before starting vitamins?
Yes, especially if your dog has health conditions or is on medication. A vet can recommend the right formulation and dosage.
