This 16 oz Pfizer Nemex bottle is the bulk version of the liquid wormer line, priced at $138.47, and while it has fewer reviews than the smaller 2 oz size, its 4.6 star average suggests it works the same way, just in a much larger quantity.
Multi-dog households, kennels, or anyone who goes through a liquid wormer often enough that a 16 oz bottle makes more sense than repeatedly buying the 2 oz size.
Skip if
You only have one dog and don't need a bulk supply, since the cost here is significantly higher than the smaller size and could go unused before it's needed again.

Overview
["This is the 16 oz bulk version of the Pfizer Nemex liquid wormer line, listed under the Wormers department. It's a much larger quantity than the 2 oz bottle also covered in this roundup, aimed at situations where you'd otherwise be repurchasing the small size often.", "As with the smaller bottle, this listing doesn't spell out the active ingredient or which specific parasites it targets, so that's worth confirming on the physical label or with your vet if it matters for your situation.", "At $138.47, it's by far the most expensive product in this dewormer lineup, though on a per-ounce basis it may work out cheaper than repeatedly buying the 2 oz size. With 291 reviews at a 4.6 star average and about 50 units bought in the past month, it sees far less turnover than the smaller bottle, consistent with being a bulk, less frequently purchased size."]

Performance notes
Being a liquid, this bottle is dosed by measuring rather than mixing into food or giving a tablet, the same basic format as the smaller Nemex bottle, just scaled up for higher volume use.
What buyers say
With 291 reviews at a 4.6 star average and roughly 50 units bought in the past month, this bulk size sees much less traffic than the smaller 2 oz bottle, which tracks with it being a higher-cost, lower-frequency purchase.
Is this the same formula as the smaller 2 oz Nemex bottle?
It's part of the same Pfizer Nemex liquid wormer line, just in a much larger 16 oz size. The listing doesn't detail exact formula differences, if any, between sizes.
Who is the 16 oz size meant for?
This bulk size makes more sense for multi-dog households or anyone who would otherwise be repurchasing the smaller 2 oz bottle frequently.
Should I check with a vet before buying this size?
This is not veterinary advice. Given the higher cost and bulk quantity, confirming dosing and the active ingredient with your vet before buying is a reasonable step.
