Frequently Asked Questions
Your dog does not get all of the active nutrients they need from their food alone. When we assume they get everything they need from their diet, dogs miss out on additional health benefits that target specific health conditions.
SEE ALL
Doesn’t my dog get all the necessary nutrients in their food?
Your dog does not get all of the active nutrients they need from their food alone. When we assume they get everything they need from their diet, dogs miss out on additional health benefits that target specific health conditions. They also don’t get antioxidants and anti-inflammatory ingredients, joint support, and more. Aside from being repetitive and flavorless oftentimes, your dog’s food isn’t doing more for them when it comes to their nutrition. Supplements with active ingredients can help dogs absorb more nutrients.
Why and when should I give my dog supplements?
You can start giving your dog supplements when they’re a puppy for preventative care if they’re a working or sport dog to recover, or a senior dog who needs support in their older age. Dogs of all ages benefit from bioavailability with BioPup.
What are the concerns that would require me to give my dog
BioPup™ Canine Functional Joint Health complex?
Osteoarthritis can occur in different parts of your dog’s body: hip joints (hip dysplasia), elbow joints (elbow dysplasia), ankles, knees, and spine. BioFlexine helps keep joints healthy in active and athletic dogs, and it’s beneficial for aging dogs improving their quality of life and freedom of movement. It can also help with post-injury recovery.
Is PupFlex+® recommended by veterinarians?
Yes! PupFlex+® was reviewed, tested, certified and recommended by veterinarians from a VCPR - Veterinary Client-Patient Relationship organization. Our VetEvaluated seal confirms quality of the product.
