Neutered and spayed dogs can sometimes require a more specialist diet. This is because increased appetite and higher energy needs are often a result of sterilisation - something which can lead to weight gain. If you find your dog is struggling with their weight and are worried, speak to your vet in the first instance. It may be that they advise a diet specially tailored to the needs of your pet. We offer a variety of sterilised dog food options, from Hill's Adult Lite, to Royal Canin Sterilised Care and Pro Plan Optiweight Light Sterilised Dog Food.
