The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Overview
["This 12 oz powder is Under the Weather's milk based counterpart to their goat milk formula, built around a dog and puppy milk flavor with added colostrum and vitamin B12. It's formulated for sensitive digestion and labeled for all life stages and all dog breeds rather than one narrow age or size window.", "The recommended uses on the listing are broad, covering growth support, recovery aid, and overall health support, and the brand markets the colostrum addition as included for immune support. As with any supplement, this isn't a substitute for veterinary care if your dog has a specific medical condition.", "At $25.99 for 12 oz, it's priced below its goat milk sibling from the same brand. With 39 reviews and a 4.4 star average, it's the smallest review sample in this group, so it's still building a track record, but early feedback is positive."]

Performance notes
The combination of colostrum and vitamin B12 targets immune and general health support, and the sensitive digestion claim suggests the recipe is built to be gentle on a developing or recovering gut. Because this is the milk based version rather than the brand's goat milk alternative, it may be worth comparing the two if your dog has a known dairy sensitivity, though neither is a substitute for veterinary guidance on a specific health issue.
What buyers say
With only 39 reviews, the 4.4 star average is a smaller and newer sample than most other products in this category, so it's a promising early signal rather than a fully proven track record yet.
How is this different from Under the Weather's goat milk version?
This is the brand's traditional milk based formula, while their other product uses a goat milk base. Both include colostrum, so the choice mostly comes down to which base your dog tolerates better.
What life stages is this formula meant for?
The label lists it for all life stages and all dog breeds, and recommended uses include growth support, recovery aid, and overall health support rather than one narrow age window.
Can this replace veterinary care for a sick puppy?
No, this is a nutritional supplement, not veterinary treatment. If your puppy is ill or failing to thrive, contact your vet promptly rather than relying on a supplement alone.
