Dog Vitamins and Supplements at PetSmart 

Ensuring your dog's health and well-being is paramount, and at PetSmart, we provide a diverse range of dog vitamins and supplements to support their needs. Whether you're addressing joint health, digestion, or general wellness, our selection includes top brands like Cosequin and Denamarin, specially formulated to enhance your dog's quality of life. 

Why Your Dog Needs Supplements 

While a balanced diet provides most of the necessary nutrients for your dog, supplements can fill specific nutritional gaps, especially as your pet ages or faces health challenges. For example, probiotics for dogs help maintain gut health, while joint supplements like Cosequin assist in improving mobility. 
  • Joint Support: Products like Cosequin and Dasuquin support healthy joint function, particularly beneficial for older dogs or breeds prone to joint issues. 
  • Digestive Health: Probiotics such as those from Zesty Paws help manage digestion, reduce gas, and improve nutrient absorption. 
  • Liver Function: Denamarin is specifically formulated to support liver health
  • Calming Aids: Calming treats for dogs can reduce stress and anxiety, providing a natural solution during travel or thunderstorms.

Frequently Asked Questions (FAQs) 

What is the best overall vitamin for dogs? 

Choosing the best vitamin depends on your dog's specific needs. Multivitamins that support overall wellness, such as those from Zesty Paws, are often recommended by veterinarians. 

Can I give my dog vitamins every day? 

Yes, many vitamins are safe for daily use, but it is crucial to follow the dosage instructions on the product label or consult your veterinarian. 

How do I know if my dog needs vitamins? 

Signs like lethargy, poor coat condition, or specific health issues may indicate a need for supplementation. Consulting with your veterinarian can help determine the right vitamins for your pet. 

What vitamins should dogs not have? 

Some human vitamins, such as iron or vitamin D at high levels, can be toxic to dogs. It is always important to use products specifically designed for canine use.
