Most of you might be confused between pet vitamins and supplements. Of course, you should be aware whether to give your dogs health supplements or vitamins.

Do Dogs Need Nutrient Supplements and Vitamins?

Yes. Some dogs lack specific nutrients or need an increase of a particular vitamin to improve their coat, teeth, or overall health. Giving them a punctual supplementation, as advised by their vet, is going to balance their health and let them get what they are missing or needing.

Some dogs may receive a balanced diet with vitamins and minerals especially if you’re feeding them commercial dog food.

How to Choose a Dog Vitamin?

Not all dogs have the same weight and health condition, it’s important to know the right amount of dosage before giving vitamins and supplements to your dogs. Veterinary consultation can also help you know what are problems your dogs are encountering. Since our dogs may seem okay physically, we still don’t know if they’re okay on the inside so better leave it to the experts.
