Ivet dog food is it a good food or no

[Taliasun]

Also, if your vet put your pet on a diet for weight loss and not another kind of issue like diabetes, renal disease or bladder health, there are plenty of fishies in the sea that are lower calorie.
I'd start with getting your vet to give you an estimate of your pet's ideal weight, look and see how many calories your current food is (including treats and people food) and use https://www.dogfoodadvisor.com/dog-feeding-tips/dog-food-calculator/ to configure the amount per day you should be feeding.
