By Marcus Bell · Dog nutrition editor · Published 2026-06-04 · Updated 2026-06-28
ZENO's chicken flavored chew is marketed as an 11-in-1 muscle and weight gain formula aimed at bully breeds and other dogs looking to bulk up, and its 4.2 star rating across 53 reviews suggests decent early satisfaction, though rapid weight or muscle gain supplements deserve a careful look before use, especially in growing puppies.
Owners of lean adult bully breeds or other dogs who need extra calories and amino acid support to gain healthy weight or muscle, under a vet's guidance.

You have a large or giant breed puppy, since accelerating growth or weight gain in growing large breed puppies can affect joint and bone development, or your dog is already at a healthy weight.

Overview
['Marketed as an 11-in-1 formula, this chicken flavored chew from ZENO combines high protein and amino acids and is positioned as a muscle builder for bully breeds and other dogs, sold in a 150 count bag.', 'The listing calls out puppies as an intended user alongside adult dogs, but weight and muscle gain products used on growing large breed puppies are worth discussing with a vet first, since rapid growth can affect developing joints and bones.', "At $7.99 for 150 chews, it's one of the most affordable options in this category, and its 4.2 star rating across 53 reviews points to reasonably positive early feedback for a budget friendly muscle and weight gain chew."]

Performance notes
The chew combines high protein and amino acids in a chicken flavor, formulated to support weight and muscle gain rather than general antioxidant or joint maintenance. Because it's positioned for bully breeds and puppies alike, owners of growing large breed puppies should check with a vet before using any product designed to accelerate weight gain, since growth rate matters for joint development.
What buyers say
With 53 reviews and a 4.2 star average, plus about 100 bought in the past month, this is a modestly reviewed but reasonably well-liked budget option in the muscle and weight gain space.
The listing includes puppies as an intended user, but any supplement meant to speed up weight or muscle gain should be reviewed with your vet first, especially for large breed puppies, since fast growth can affect joint and bone development.
What does 11-in-1 refer to?
The listing markets it as combining multiple ingredients and benefits, high protein and amino acids aimed at muscle and weight gain, in one chew, though the label doesn't break down all 11 components individually.
Is this meant for dogs that need to lose weight?
No, this is formulated as a weight and muscle gain supplement, the opposite of a weight management product, so it's meant for lean dogs that need to add weight, not dogs that need to slim down.
