Overview
["This chewable tablet supplement from Nutramax is built around Crananidin, a proprietary cranberry extract the brand describes as veterinary researched, delivering 93 mg of cranberry extract equivalent to 16 mg of proanthocyanidins per dose. It's formulated to support normal bladder health and urinary tract function in dogs.", 'Each package includes two bottles of 75 count each, for 150 chewable tablets total, and the cranberry flavor is meant to make daily dosing straightforward. Nutramax is a well known name in veterinary supplements, which lends some credibility to the specific extract formulation used here.', 'At $99.98 for 150 tablets, the per-tablet cost is higher than many general cranberry chews, reflecting the branded extract and larger multi-bottle pack. With 2,000 reviews and a 4.7 star average, it has both a large sample size and one of the strongest ratings in the herbal supplement category.']

Performance notes
The tablet form with a cranberry flavor is designed to be palatable enough for daily chewing rather than needing to be hidden in food, and the specified 93 mg cranberry extract dose with a stated proanthocyanidin equivalent gives owners a clearer sense of what's in each tablet compared to supplements that just list a proprietary blend without amounts.
What buyers say
A 4.7 star average across 2,000 reviews reflects a large, consistently satisfied buyer base, though the bought-last-month figure was not available at the time of writing, which is typical for a higher-priced, multi-bottle supplement bought less frequently but in bigger quantities.
Crananidin is Nutramax's name for its proprietary cranberry extract, which the brand states is researched for proanthocyanidin content and formulated to support normal bladder and urinary tract health in dogs.
How many tablets are in this package?
This listing includes two bottles of 75 tablets each, for a total of 150 chewable tablets.
