Overview
Solid Gold's cranberry supplement is a powder built around cranberry, a common go-to ingredient for dogs prone to urinary tract irritation. It comes in a 3.5 ounce jar with a cranberry flavor, and it's formulated for dogs of all life stages, so it can fit into a household with both puppies and seniors.
The formula is free of gluten, soy, wheat, and sulphites, which makes it a reasonable pick for dogs that react to common fillers in other supplements. Because it's a powder, it mixes into wet or dry food rather than requiring a separate chew or pill.
With 934 reviews at a 4.5-star average and about 100 purchases a month, it has a solid, if modest, following among owners managing recurring urinary tract concerns.

Performance notes
Formulated as a cranberry-flavored powder with antioxidant content aimed at urinary tract control, the gluten-free, soy-free, and wheat-free label makes it a reasonable option for dogs with common food sensitivities, though it's built for daily maintenance rather than treating an active problem.
What buyers say
With 934 reviews averaging 4.5 stars, most feedback points to the powder mixing in without a fuss and fitting into a daily routine for urinary health, though around 100 purchases a month is a comparatively modest base next to some higher-volume competitors.
