My dog loves the taste
My dog is very picky and for the past three days has refused any of his food. Today as soon as it came I sprinkled it on his food and he ate it all. Very happy so far

Game changer
Our dog had been struggling to maintain weight after a long illness, and we were starting to get worried. We tried the Buddy & Lola Weight Gainer on a friend’s recommendation, and it’s been an absolute game-changer.Within a few weeks, we noticed a healthy weight gain, but what really surprised us was the improvement in his coat and skin. His fur looks shinier, feels softer, and he’s no longer scratching as much.He loves the taste too, which makes feeding time so much easier. This isn’t just a weight gainer — it’s a brilliant all-round health boost. Highly recommend if your pup needs help putting on healthy weight!

Perfect for My Rescue Dog
My rescue dog was underweight and struggling to gain. After adding Weight Gainer to his meals, I noticed a big improvement. He loves the taste, and it’s easy to use. I appreciate the high-quality ingredients with no fillers. It’s given me peace of mind during his recovery. Highly recommend this for any dog needing to gain weight!
