DOG MOBILITY SUPPLEMENT

DOG MOBILITY SUPPLEMENT

The all-natural choice for canines with 6+ active ingredients to support an ongoing active and happy life! 

The all-natural choice for canines with 6+ active ingredients to support an ongoing active and happy life! 

Add vet recommended ingredients to your dog’s daily diet to help promote ongoing mobility, aid stiffness, and support healthy joints! 

1. Glucosamine

Glucosamine HCl is a naturally occurring amino sugar that acts as a building block for cartilage and helps to keep joints supple. Glucosamine is the protestor for the health of your dog’s joints - linking arms in the face of a threat to protect your dog’s sensitive bones.

2. Green-Lipped Mussel containing Chondroitin

Rich in Omega-3 fatty acids and a natural anti-inflammatory, it aids stiff joints allowing a greater range of motion. An incredibly potent ingredient acting as a knight would defend a kingdom, it’s the first-line defense slowing inflammatory attack.

3. Turmeric & Black Pepper 

Curcumin in Turmeric has potent natural anti-inflammatory properties to promote comfort, and Turmeric has anti-oxidant potential. Think of Turmeric like a protective shield for all the free radicals signaling to your dog’s body to mount an attack.

4. Boswellia Serrata

Traditionally used in herbal remedies for its anti-inflammatory properties, Boswellia Serrata also assists Glucosamine in protecting cartilage degradation. A secret weapon in your dog’s health, this natural ingredient will protect and serve.

5. Fish Oil Powder

Full of Omega-3 fatty acids, which don’t occur naturally in the body, Fish Oil provides plenty of anti-inflammatory protection for joints. Imagine the fluidity of a fish and see how adding this oil to your dog’s body will create much-needed lubrication for stiff joints.

6. Collagen

Collagen is the main structural protein in cartilage, also found in a variety of connective tissues. Boosting collagen helps support healing potential. Consider collagen as the yarn, knitting together your dog’s body.
