Overview

Hartz's powdered milk replacer is formulated to match a mother dog's milk for puppies, and is also marketed for pregnant, nursing or convalescing dogs. It comes as a 12 oz grain-free powder in a tub, fortified with calcium, magnesium, vitamin A and linoleic acid.

Being a powder, it needs mixing before feeding, and mixing directions aren't in the spec data so buyers should follow the tub's own instructions. The listing files it under a veterinary diet food type and recommends medium breeds, worth checking against a vet's guidance for very small or giant-breed puppies.

Who it's for

Owners bottle-raising orphaned or separated puppies, or supplementing a pregnant, nursing or recovering dog's diet, who need a shelf-stable powdered formula rather than a fresh substitute.
