Appetite stimulant

Our irresistible chicken flavour supports a healthy appetite and provides easy-to-digest calories for dogs who are sick, ageing or fussy.

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 💖

Helped my chihuahua gain weight

I add this product to my little dog’s evening meal and she’s starting to gain weight. She’s elderly, a fussy eater and had been through an op. My dog enjoys her food with this powder mixed in it. It’s expensive for me so I cannot use it long term, but great as a quick fix. I therefore recommend this product.

Works a treat!

Great product, we had issues with our 2 year old Cocker Spaniel holding any weight on. Mainly as super active but was eating tins of good quality dog food and just no weight. A scoop of this a day has really helped add some weight to him and he looks alot healthy for it! Cant recommend enough!

We have a very busy cocker, that burns more than he eats! Unfortunately this product did not agree with his extremely sensitive tummy. Also, this product arrived in less than 24 hours, brilliant when you trying as much as you can to help your dog.

Absolute God-Send for our Pooch with IBD

Our Northern Inuit has IBD, and lost over 10kg in a very short space of time. It tooks months of testing with the vets to find the foods he couldn't have so in this time he lost a lot of weight, would only eat every few days and would become very anxious at mealtimes, and this was all around 9 months old. Once we found the food he could eat, we found this product and put him on it and it has been a life saver. Even on the right food, he really struggles putting weight on because he has a naturally fast metabolism also. But this has helped him get back up to 38kg. It has also helped encourage him to eat when he has previously struggled or been in a flare up. I cannot recommend this product enough!

I purchased weight gainer for my 15 month labrador Lucy as I couldn't get her to put on weight. She has finished her first bag and I have just ordered her second one. The results have been amazing and she looks so good and in great condition. Many thanks to Buddy and Lola for this amazing product.
