Ace Antlers, the Scotland-based pet brand that has built a loyal following for its range of natural antler chews, has moved into new territory with the launch of Muzzle Mass — a venison-flavoured weight gainer for dogs that the company says is designed to support everything from muscle building and weight management to post-surgery recovery and appetite stimulation.
The product has been developed in-house by the brand in collaboration with a leading canine nutritionist and is already generating significant interest among dog owners, trainers, and veterinary professionals alike.
A Simple Formula in a Crowded Market
What sets Muzzle Mass apart in an increasingly busy pet supplement space is its strikingly minimal ingredient list. The product contains just four ingredients — milled venison powder, antler powder, coconut powder and carrot powder — and the brand has been vocal about the absence of fillers, artificial additives, or cheaper substitute meats that are common in rival products.
The venison used is sourced from wild deer, free from hormones and antibiotics, and is gently air-dried and milled into a coarse powder.
The antler powder, a by-product of the company's core antler chew production, is vacuum extracted and heat treated, providing a natural source of protein, B2 vitamins and minerals.
Coconut powder delivers a concentrated source of natural fats, while carrot powder rounds out the formula as a digestive aid.
The recipe is also hypoallergenic, making it suitable for dogs with sensitive stomachs — a notable selling point given that food sensitivities are among the most common health complaints reported by dog owners in the UK.
Who Is It For?
Ace Antlers has positioned Muzzle Mass as a versatile supplement rather than a niche product for underweight dogs alone. The brand identifies six primary use cases: weight gain, weight management, muscle building, appetite stimulation, recovery support and palatability for fussy eaters.
From a nutritional standpoint, each 100g of Muzzle Mass contains 500 calories, 15g of protein, 41g of natural fats and 28.5g of carbohydrates.
The feeding recommendation is one scoop — approximately 40g — for every 10kg of body weight, mixed with an equal quantity of hot water to form a paste and added to the dog's regular food.
The brand is careful to note that Muzzle Mass is not recommended for dogs with pancreatitis, given its relatively high fat content, and advises owners of dogs with underlying medical conditions to consult a veterinarian before introducing the supplement.
Addressing a Gap in Canine Health Conversations
Behind the launch is a broader message about canine health that Ace Antlers is keen to promote.
While public awareness of pet obesity has grown considerably in recent years, the brand argues that unintentional weight loss and age-related muscle wastage are equally serious issues that receive far less attention.
The product page, which reads almost like a veterinary white paper, outlines in considerable detail the risks associated with muscle atrophy in ageing dogs, the role of strong muscle condition in injury prevention, and the nutritional demands placed on dogs recovering from illness or orthopaedic surgery.
The company references veterinary and orthopaedic research to support the case that muscle maintenance through nutrition is a preventative health strategy, not merely a cosmetic concern.
It is a positioning that feels timely.
The pet wellness industry has undergone considerable professionalisation in recent years, with dog owners increasingly seeking products that reflect the kind of evidence-informed approach they would expect in their own healthcare.
Ace Antlers appears to be banking on that shift.
From Antlers to Supplements: A Natural Evolution
For a brand built on one of the most natural dog chews available, the move into supplements is a logical one.
Antler powder — already a core component of the company's production process — forms part of the Muzzle Mass formula, meaning the new product is as much an extension of existing operations as it is a diversification.
The company has also made clear that Muzzle Mass is manufactured in-house, which will likely reassure buyers concerned about quality control. Muzzle Mass is available now at aceantlers.com.
