SquarePet VFS Low Phosphorus Formula Dry Dog Food

Low Protein, Low Phosphorus, Low Sodium Kibble for Dogs with Kidney Concerns 

Product Description

SquarePet VFS Low Phosphorus Formula is a veterinarian-formulated dry dog food providing targeted low phosphorus, low protein, and low sodium nutrition for dogs whose veterinarians have recommended these dietary restrictions. Cage-free turkey and cage-free whole eggs from named US farms provide highly digestible protein at reduced levels, while salmon oil delivers EPA and DHA omega-3 fatty acids. Intended for intermittent or supplemental feeding as directed by your veterinarian. Available without a prescription.

Benefits 

• Guaranteed Phosphorus Range: Both a minimum and maximum phosphorus level are confirmed in the guaranteed analysis, giving veterinarians and owners precise dietary control over phosphorus intake.
• Guaranteed Low Sodium Range: Sodium is also guaranteed within a defined range, providing the full low-phosphorus, low-protein, and low-sodium nutritional trifecta in a single formula.
• Cage-Free Turkey and Whole Eggs for Digestibility: Cage-free turkey from South Dakota and cage-free whole eggs from California are the primary protein sources, chosen for their digestibility and palatability at reduced protein levels.
• High EPA and DHA from Salmon Oil: Salmon oil provides omega-3 fatty acids with meaningfully higher levels of EPA and DHA than typical maintenance dog foods.
• Bacillus Coagulans Probiotic for Gut Health: A shelf-stable Bacillus Coagulans probiotic supports a healthy gut microbiome in dogs on this long-term specialized diet.

Disclaimer: Product information and usage guidelines are provided by the manufacturer. Always use products as directed on the label and consult your veterinarian before use if you have any concerns regarding your pet’s health. 

Directions for Use   

• Use as directed by your veterinarian: This is a specialized diet for dogs with specific medical needs.
• Transition gradually: Mix a small amount of this food with your dog's current food and shift the ratio over 7 to 10 days to ease the transition, especially for dogs already managing a digestive or kidney condition.
• Keep water available at all times: Fresh, clean water must always be available; adequate hydration is especially important for dogs on a low-sodium, kidney-supportive diet.

Additional Information

Precautions  

• Not a complete and balanced diet: This food intentionally restricts phosphorus, protein, and sodium below AAFCO complete and balanced minimums. It is labeled for intermittent or supplemental feeding only.
• Use under veterinary supervision: This is a therapeutic nutrition product for dogs with specific health needs.
• Account for treats carefully: Any treats given alongside this diet can affect the total daily phosphorus, protein, and sodium intake.

Storage Information

• Seal the bag after each use: Roll or clip it shut after every feeding. Leaving it open lets air and moisture in, and the kibble goes stale faster than expected.
• Cool and dry storage: Keep it somewhere cool and out of direct sun. A warm, humid spot degrades fat content faster and shortens shelf life.
• Do not refrigerate: Kibble doesn't need refrigeration, putting it in the fridge causes condensation inside the bag which introduces moisture and can lead to mold.

Frequently Asked Questions

Q1: Why does this food say "intermittent or supplemental feeding only"?

Ans: AAFCO requires this label when a food deliberately restricts nutrients below the minimum levels required for a complete and balanced classification. This formula intentionally lowers phosphorus, protein, and sodium to levels that benefit dogs with kidney concerns.

Q2: What are the exact phosphorus, protein, and sodium levels guaranteed?

Ans: All three are confirmed in the guaranteed analysis on the product label with both minimums and maximums where applicable. Consult your veterinarian to confirm whether these levels align with your dog's specific dietary targets.

Q3: Why does this formula include high levels of EPA and DHA?

Ans: EPA and DHA from salmon oil help support kidney function and overall kidney health. Their elevated levels make this formula specifically suited for dogs with kidney support needs rather than everyday maintenance.

Q4: Do I need a prescription to buy this food?

Ans: No. This food is available over the counter from SquarePet and independent pet retailers without a veterinary prescription. Working with your veterinarian to confirm it is appropriate for your dog, determine correct daily amounts, and schedule regular bloodwork monitoring.

Q5: Why are protein levels intentionally low in this formula?

Ans: Lower protein helps reduce the kidneys' workload. The formula uses highly digestible protein sources, such as cage-free turkey and whole eggs, to maximize nutrient absorption.
