TL;DR: Grober Pets Puppy Gro Milk Replacer is a Canadian-made powdered formula for puppies aged 0–8 weeks who are orphaned, rejected, or need supplemental feeding alongside nursing. It mixes with warm water and is made for breeders, rescues, and new puppy caregivers who need a reliable alternative to canine milk.

When a puppy can't nurse from its mother, a purpose-built milk replacer is the safest way to support those critical first weeks. Puppy Gro is formulated for the nutritional needs of puppies during the 0–8 week window, before they transition to solid puppy food.

Specifications

Who is it for?

This milk replacer is made for puppies who are orphaned, rejected by the dam, part of an oversized litter, or need supplemental feeding to keep pace with littermates. It's a practical tool for breeders, foster families, and rescue organizations, as well as first-time caregivers raising a puppy from its earliest days.

Newborns are fragile, and steady nutrition matters long before a pup is ready for solid food. If you're caring for more than one species, the Grober Pets - Kitten Gro Milk Replacer covers orphaned kittens, and among dog health and wellness products the CartiKare - Dog & Cat Chews For Joints supports joint health once your dog is older. Multi-pet households welcoming a new puppy may also consider the Feliway - Classic Diffuser to help resident cats settle.

Feeding & use

Mix the powder with warm water according to the package instructions and feed at body temperature using a clean bottle or syringe sized to the puppy. Prepare fresh formula at each feeding and refrigerate any unused reconstituted milk as directed on the label.

Feeding frequency depends on age and weight — very young pups typically need small, frequent feedings around the clock, tapering as they grow. Consult your veterinarian for a schedule specific to your puppy, especially for newborns under two weeks of age.

How long should puppies stay on a milk replacer?

Puppy Gro is intended for puppies from birth through about 8 weeks of age, with gradual weaning onto puppy food usually starting around 3–4 weeks. Your veterinarian can confirm the right transition timing for your litter.

Why choose Grober Pets for early puppy care?

Grober Pets makes species-specific milk replacers in Canada, so you can match the formula to the animal you're raising rather than improvising with a substitute. Neonatal nutrition sits at the foundation of any list of top dog health and wellness priorities, since the first eight weeks set the pace for a puppy's growth.
