Ace Antlers, a UK-based brand known for its natural dog chews and supplements, has announced the launch of Muzzle Mass, a natural weight gainer for dogs designed to support healthy body condition, muscle maintenance and nutritional intake in dogs that struggle to maintain weight.
The product launch reflects a growing conversation within the pet industry around healthy ageing and condition management, with increasing recognition that maintaining the correct weight in dogs is not solely about preventing obesity. For many dogs — particularly senior dogs and those with higher physical demands — unintentional weight loss and muscle depletion can present equally serious welfare concerns.
As dogs age, physiological changes can affect how efficiently nutrients are absorbed and utilised. Appetite may decrease, activity levels may fluctuate, and muscle mass can gradually decline over time. This loss of lean muscle, often referred to as age-related muscle loss, can impact balance, joint stability, mobility and overall resilience. In working and highly active dogs, similar challenges can arise due to sustained energy output and recovery demands.
Ace Antlers developed Muzzle Mass to help address these issues through a functional, clean-label supplement that supports condition without unnecessary complexity. The powdered formulation is made using four natural ingredients — coconut powder, venison powder, antler powder and carrot powder — and contains no artificial additives, preservatives, fillers or bulking agents.
The focus of Muzzle Mass is on gradual, controlled weight and condition support, rather than rapid or excessive weight gain. By prioritising nutrient density and digestibility, the supplement is intended to help dogs maintain strength and condition over time, making it suitable for both short-term recovery use and longer-term nutritional support.
Muzzle Mass has been developed for a broad range of dogs, including underweight dogs, senior dogs experiencing age-related muscle loss, dogs recovering from illness or surgery, and working or sporting breeds with elevated nutritional requirements. The inclusion of venison supports palatability, which can be particularly beneficial for dogs with reduced appetite or selective eating habits, while the powdered format allows for easy integration into existing diets.
A spokesperson for Ace Antlers said:
“Weight management is often discussed in terms of avoiding excess weight, but maintaining adequate weight and muscle is just as important — especially as dogs get older. Muzzle Mass was created to offer a natural, straightforward option for supporting condition and recovery without relying on artificial ingredients or heavy fillers.”
The supplement is designed to be mixed with a dog’s usual food, allowing owners and professionals to adjust portions based on size, age, activity level and individual needs. This flexibility makes Muzzle Mass particularly relevant for canine professionals, trainers, groomers and independent retailers, who frequently encounter dogs with varying dietary and condition-related challenges.
From a trade perspective, the product aligns with broader trends toward preventative health, functional nutrition and transparency, as consumers become increasingly informed about ingredient quality and long-term wellbeing. Products that support healthy ageing and condition management are seeing increased interest, particularly as dogs live longer and owners seek solutions that prioritise quality of life rather than short-term fixes.
Muzzle Mass also complements Ace Antlers’ existing range of natural dog products, which includes antler chews and supplements designed to support chewing behaviour, dental health and nutritional balance. The addition of a weight and condition support product reflects the brand’s continued investment in practical solutions that address real-world feeding concerns faced by dog owners and professionals.
By focusing on recognisable ingredients and clear functionality, Ace Antlers aims to provide products that can be confidently recommended by retailers and professionals, while remaining accessible to informed pet owners seeking natural options.
