Solid Option
This is a hydration-focused supplement rather than a complete food, intended to be added to your dog’s water. It offers electrolytes, amino acids, and collagen, which can be helpful for active dogs, working dogs, or pets needing extra support during hot weather or after exercise. It should be used alongside a balanced diet, not instead of regular dog food.

Strengths
- Formulated specifically to support hydration by adding electrolytes like sodium, potassium, magnesium, and calcium to your dog’s water.
- Includes bovine collagen and amino acids, which may help support joint, muscle, and connective tissue health over time.
- Contains zinc and vitamin B12, which play roles in immune function, energy metabolism, and overall wellness.
- Powdered, single-serve packets make it easy to mix into fresh water for dogs of any size or age.
Considerations
- This is not a complete and balanced diet, so it must be used only as a supplement alongside your dog’s regular food.
- The formula includes natural flavors, which may not suit very sensitive dogs that react to flavor additives.
- Because it changes the taste of water, some dogs may drink more, but picky dogs might drink less if they dislike the new flavor.

Top 5 Ingredients Explained
01
Collagen Peptide
Collagen peptides are hydrolyzed collagen proteins used in pet foods and supplements as a highly digestible source of structural amino acids (notably glycine, proline and hydroxyproline) and are commonly added to joint, skin and coat formulas for dogs and cats to support connective tissue and mobility. They can provide targeted support for aging or active pets but are not a complete protein source of all essential amino acids, so they should complement a balanced diet; owners should choose products from reputable sources and note that palatability and measurable benefits can vary.
02
Beef Collagen
Beef collagen, derived from bovine connective tissues, is used in pet foods and treats as a source of collagen peptides to improve texture and potentially support skin, coat and joint connective tissue in dogs and cats. It supplies amino acids such as glycine and proline but is not a complete protein for growth, may cause reactions in animals with beef sensitivities, and any joint- or skin-support claims should be viewed as supportive rather than curative and discussed with your veterinarian.
03
L-Alanine
L-Alanine is a non-essential, proteinogenic amino acid used in pet foods and supplements as a building block for proteins and to support energy metabolism through the alanine–glucose cycle. Dogs and cats can synthesize alanine so it is typically unnecessary in complete diets, though it can aid tissue repair and nitrogen transport; high-purity supplementation is generally safe but unnecessary in balanced formulas and excessive isolated amino acids can disrupt overall amino acid balance.
04
Rice Bran
Rice bran, the nutrient-rich outer layer of the rice kernel, is used in pet foods as a source of dietary fiber, energy-dense fats, and micronutrients (B vitamins, vitamin E and trace minerals) and can help improve palatability and stool quality. It can be a useful ingredient for dogs (and to a lesser extent cats) but is high in oil and can go rancid unless stabilized, contains phytates that may affect mineral absorption, and can concentrate contaminants like inorganic arsenic, so it should be sourced and processed carefully and not be relied on as a primary protein for obligate carnivores.
05
Natural Flavor
Natural flavor is used primarily as a palatability enhancer in pet foods to improve taste and aroma and is not intended to provide significant nutrients, typically coming from concentrated extracts of meat, poultry, plant, or fermentation sources. While it can increase acceptance in picky dogs and cats, manufacturers are not required to disclose specific sources so pets with known sensitivities or allergies may react, and presence of natural flavor should not be taken as a guarantee of overall product quality.
