Weight Gainer for dogs

High Calorie Supplement for Dogs

"My Springer’s always struggled to keep weight on, mainly because he’s a fussy eater. Since using Weight Gainer, he’s finally started to gain weight, fill out, and has never looked healthier 😍 Even my family’s noticed 🙊"

― Jean M.
  • High quality protein to help dogs grow bigger, stronger & healthier

  • Convenient way to add extra calories without adding extra meals

  • Irresistible flavour to encourage fussy eaters and sickly dogs

  • If your dog also needs help to calm 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!

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.

Ageing, sick, recovering or finicky dogs...or even dogs refusing their food, often require extra calories and nutrients to provide the nutritional support they need and Weight Gainer is the perfect weight gain supplement for dogs.

We rescued Suzie from a puppy farm where she hadn't been fed properly while supplementing milk for her puppies 😢 She had low muscle mass as a result. But now, after two weeks of using weight gainer, her weight is finally on a steady increase 🙌

I believed this product was too good to be true - I couldn’t be more wrong. What a wonderful product my puppies love it and their mother loves it. The smell alone is so appetising. I’ve also seen first-hand the change in the weight and performance. Thank you Buddy & Lola 😁

We have struggled with Winnie's pickiness for years. If she likes things it’s only for a little while. Let me tell you... SHE LOVES Buddy & Lola, especially Weight Gainer 😛 I mix it in with her food daily. A total surprise bonus is her hair is so soft and smooth. Thank you Buddy & Lola - we love you 💖
