Started feeding this to my skinny standard dachshund at 6 months. He's now 18 months old and looks as a standard dachshund should look. Good weight, stunning shiny coat and eyes with bags of energy. I am now gradually reducing the amount he gets as winter is coming and my dogs aren't keen on long winter walks in the cold, rain and mud. Frankly neither am I.

Spent months trying to get my 9 month old pup to stop being so thin and looking so bony. Tried quite a few foods and made no difference and wasn’t happy feeding my dog rubbish. I read about Peak performance and in around 2 months he has gained almost 2kg and looks soo much better, healthier and I’m much happier! I was well aware he couldn’t always stay on this but I think once a year I will go back to this to help my dog keep his weight on. He is a pet working gun dog, very athletic and gets tonnes of exercise which is why he wasn’t holding down any weight as he was exerting so much energy. We are thrilled and can’t recommend this enough!!!

Tried loads of foods but nothing would help my working Lab put on weight, even "premium" foods like Eden. After a thousands of pounds of health tests all telling us he was fine a random stranger suggested we try Peak Performance. Within a matter of months he was up to his optimum weight, happy, glossy coat and plenty of energy. Totally transformed my dog. This food should be a 5.0 as it meets a specific need many working dogs and active breeds require. Common sense says don't use this high calorie food if your dog is not active or already overweight.

Not sure why this is only rated 4.2 but my Hungarian Vizsla has always been too skinny until I discovered this food. He looks the best he has ever looked and I think it's down to the fact that 1. it has more fat so obviously this is a big factor but 2. slightly less protein than some foods which seems just the right balance for him because if it's too high in protein he just squits it out. I think he will be on it long term as the slightest thing makes him lose weight.

My GSP has always been on the light side even when on 5* rated foods. I research the calorie contents of feeds and came across this. Within days I could see a difference and 3 weeks later he looks fantastic. Never looked as well. Whether he'll stay on it long term I don't know, but thoroughly recommend if you need to put weight on a dog with good ingredients!

I would endorse the two previous comments about this food, my young active working cocker was too skinny "running it off and squitting it out", and a few months on Peak Performance (on manufacturer's recommendation) solved the problem. He is now a healthy weight and on the Endurance mix, but Peak Performance resolved months of worry.

Is this food rated down because it is above average fat?
My dogs and many other working type gundogs struggle to maintain weight and this food is specifically geared to these needs. It shouldn't be marked down for meeting a need which no other good quality food seems to be meeting.

My young English Springer Springer Spaniel was really struggling to put weight on. We tried a few different types of food, but nothing was helping. Peak Performance has been great, she's finally put on weight, is looking much healthier and is back to being the bouncy springer, she should be!! I will say though, we are having to feed her substantially more than the recommended amount, but she is happy and so are we.
