Under the Weather's goat milk based Puppy Milk Replacement Formula pairs colostrum with an all life stage label, and though it has a smaller review base so far, a 4.5 star average and a versatile ingredient list stand out among the more traditional dairy based replacers here.
Owners who want a goat milk based option with added colostrum, whether for bottle feeding a newborn, topping a bowl, supplementing a pregnant or nursing dog, or supporting a dog recovering from illness.

You're looking strictly for a traditional newborn-only formula, since this one is labeled for all life stages and multiple use cases, or your dog has a specific medical condition that needs a vet-directed diet.

Overview
['This 12 oz powder from Under the Weather is built on a goat milk base with added colostrum, taurine, vitamin A, vitamin D3, vitamin B12 and calcium. Unlike some of the other products here that are narrowly aimed at the newborn to six week window, this one is labeled for all life stages and lists a wide range of recommended uses.', 'Those uses include bottle feeding newborns, using it as a food topper, supplementing pregnant or lactating dogs, supporting recovery from illness, and aiding digestion generally. The brand frames colostrum as included for immune support, though as with any supplement, a vet is the right resource for a dog with a specific medical concern.', "Priced at $34.99 for 12 oz, it's on the higher end for this size compared to the dairy based options, which likely reflects the goat milk and colostrum formulation. With 46 reviews and a 4.5 star average, the sample size is smaller than the more established brands, but early sentiment is positive."]

Performance notes
The goat milk base is generally considered easier for some dogs to digest than cow's milk based formulas, and pairing it with colostrum targets immune support during vulnerable periods like early life or recovery from illness. Because the label spans multiple use cases, from bottle feeding to food topper to recovery aid, it reads as a flexible product rather than one built around a single narrow purpose, though this is not veterinary advice and a vet should guide use for any dog with an ongoing health issue.
What buyers say
A 4.5 star average across 46 reviews is a positive early signal, though the sample size is much smaller than the more established milk replacer brands in this category, so it's worth watching how the rating holds up as more owners weigh in.
No, it's labeled for all life stages and lists uses beyond newborn feeding, including as a food topper and a supplement for pregnant, lactating, or recovering dogs.
What does the colostrum do?
Under the Weather markets the added colostrum as included for immune support, but this is not veterinary advice. If your dog has a specific health concern, talk to your vet before adding a new supplement.
Is goat milk easier to digest than cow's milk for dogs?
Goat milk is often considered gentler on digestion for some dogs, which may be part of why this formula uses it as the base, though individual tolerance varies and a vet can help if your dog has ongoing digestive issues.
