Is your dog a rescue? A fussy eater? Losing weight? This high-protein, high-calorie plant based weight gain supplement is designed to help them gain weight the healthy way, whilst boosting their appetite. This tasty powder also includes amino acids to support your dog's health and wellbeing.

Tasty chicken flavour but without the meat content so this supplement is suitable for dogs who have an allergy to chicken.

Suitable for dogs over 12 weeks, including pregnant and nursing dogs. Scoop included in each 300g pouch.

If your dog also needs help with signs of anxiety or stress why not try our calming supplement Peaceful Pooch or if they're high energy our Working Dog Bundle is definitely worth trying!

    Tasty product

    My 11 year old rescue greyhound is a very picky eater. He stopped wanting his regular meal some months ago. His weight plummeted.

    After a vet check up I needed to get more calories in him. I bought the weight gainer without much hope - he won’t take medication. However, I was pleasantly surprised that he ate the powder mixed into food.

    He continues to have the powder mix without hesitation, obviously some fresh chicken helps…

    Hopefully the extra calories are helping him to get stronger so he can age more gracefully and comfortably

    Weight gain supplement

    With having a very fussy eater it has been impossible to get Finn to put on weight and he has remained exceptionally thin despite trying so many different things and being checked at the vets. He has been on the weight gain for almost 2 month and finally beginning to see improvement and less of a stick thin pooch
