PetLac Milk Replacement Powder Supplement
Verified Jun 3, 2026
This is a high-calorie milk replacement and nutritional supplement powder for dogs and cats, designed to be mixed with water. It uses dairy proteins and fats to provide a nutrient profile similar to mother’s milk, making it useful for puppies and kittens that need extra support, as well as stressed or recovering adult pets. Added vitamins, minerals, and taurine help support growth and general health when regular food alone isn’t enough.
Nutritionally, this is a well-formulated milk replacer and supplemental calorie source for both young and adult dogs and cats. The high protein and fat from dairy, along with a full complement of vitamins and minerals, make it appropriate for orphaned or supplement-needing puppies and kittens, as well as adults needing extra calories during illness or recovery. It’s best used under veterinary guidance, especially for very young or medically fragile animals.

KibbleLab Review
Strengths
- High protein (23% min) and fat (30% min) levels provide dense calories, similar in concept to mother’s milk, which can be very helpful for growing or recovering pets.
- Uses dairy-based ingredients (whey, whey protein concentrate, cream) that are generally highly digestible sources of protein and fat for most dogs and cats.
- Fortified with a broad spectrum of vitamins and minerals, plus taurine, to help support normal growth and overall health when used as directed.
- Powdered format is easy to store and allows flexible use as a milk replacer, top-dress, or added calorie source depending on the pet’s needs.
Considerations
- Because this relies on dairy ingredients, it may not be suitable for pets with known dairy sensitivities or lactose intolerance.
- This is a supplement and milk replacer, not a complete long-term sole diet for healthy adult pets, so it should generally be used alongside an appropriate complete and balanced pet food unless your veterinarian directs otherwise.
- The high fat and calorie density can be too rich for some animals, particularly if introduced abruptly or given in excess, and could lead to digestive upset.

Top 5 Ingredients Explained
01
Vegetable Oil
Vegetable oil in pet food is used primarily as a concentrated fat source to boost calorie density, improve palatability and texture, and supply essential fatty acids (typically omega‑6 such as linoleic acid) while helping absorption of fat‑soluble vitamins. It can support skin and coat health for dogs and cats, but nutrient profiles vary by oil type and most vegetable oils lack long‑chain omega‑3s and the arachidonic acid cats require; excessive fat can promote weight gain or precipitate pancreatitis in susceptible pets, so source, quality and inclusion level should be considered.
02
Whey
Whey is a dairy-derived protein and flavoring commonly used in pet foods and treats as a highly digestible, high-quality protein source rich in essential amino acids (including branched-chain amino acids) and some minerals and B vitamins. It can support muscle maintenance and improve palatability for dogs and cats, but may cause gastrointestinal upset in lactose-intolerant animals and should be avoided in pets with milk allergies or used cautiously to prevent excess calories or mineral imbalance.
03
Whey Protein Concentrate
Whey protein concentrate is a dairy-derived concentrated protein commonly added to pet foods and treats to increase highly digestible, complete protein and essential amino acids that support muscle maintenance, growth, and recovery in dogs and cats while often improving palatability. Because it contains lactose and milk proteins, it may cause digestive upset or allergic reactions in pets with dairy intolerance or sensitivity and should be used cautiously in animals with certain medical conditions (e.g., advanced kidney disease); consult your veterinarian if concerned.
04
Dicalcium Phosphate
Dicalcium phosphate is an inorganic mineral supplement commonly added to dog and cat foods to supply concentrated, bioavailable calcium and phosphorus for healthy bone and teeth formation as well as general metabolic processes. It must be used in balanced amounts (typical Ca:P targets ≈1:1–1.4:1) because improper ratios or excess phosphorus can contribute to skeletal problems in growing animals and worsen conditions like chronic kidney disease, so formulation and dosing should be carefully controlled.
05
Cream
Cream is the high‑fat portion of milk used in pet foods primarily to enhance flavor, texture and caloric density as a fat source and palatability enhancer. It provides concentrated energy and fat‑soluble vitamins but little protein, may contain lactose that can cause gastrointestinal upset in lactose‑intolerant pets, and its high saturated fat content can promote obesity or trigger pancreatitis in susceptible animals, so it should be used sparingly and avoided in pets with dairy sensitivities or fat‑restricted diets.
