Yes – fish-based dog food is an excellent choice for many dogs. Fish is a highly digestible protein source, rich in omega-3 fatty acids, which promote a healthy coat, support joint function and aid heart health. It’s also ideal for dogs with sensitivities to other proteins such as chicken or beef.

You’ve heard it before, ‘you are what you eat’ - and this is just as relevant for your pet as it is to you. A good diet is crucial to your pet’s overall health and wellbeing.

At Forthglade our aim has remained the same since we opened our doors in 1971; to produce simple, wholesome & natural meals for dogs which provide them with the nourishment they deserve. You only need to see and smell our food to appreciate the quality.

All of our wet recipes are hypoallergenic. This means we carefully select our ingredients to ensure that our recipes are of the best quality for your four legged friend. We use simple, quality ingredients with no junk or nasties. This means delicious and nutritious recipes that are kind and gentle to your dogs tummy.

Our Forthglade recipes are natural (with added vitamins and minerals in our complete ranges and selected treats). Each wet recipe is free from artificial colours and flavours.

We live by a ‘free from junk and fillers’ promise, so you can be confident your four-legged friend is getting wholesome, quality nutrition at mealtimes.

When changing a pet’s diet it’s crucial to do it gradually in order to be gentle on their digestive system.

Ideally the new diet should be added to their current food in very small portions over a 5 day period, increasing this small amount each day until eventually you are feeding your pet 100% Forthglade.

Here is some advice from Dr James Greenwood, Media Vet and Forthglade Ambassador:

"When transitioning your dog onto a new diet, it is particularly important to do this gradually and to avoid any sudden changes. This allows your dog’s digestive system to adapt with the switch and remain in balance. As a minimum, allow 5 full days to gradually reduce their current diet whilst simultaneously increasing their new food with each meal. For dogs with sensitive tummies, go even slower and transition over 1-2 weeks"


Explore our wholesome range of fish dog food, ideal for dogs who thrive on a fish-based diet. Naturally rich in omega-3, our dog food with fish supports healthy skin, a glossy coat, and overall well-being. Choose from wet, dry and treat recipes, all carefully crafted to meet your dog’s nutritional needs.

Fish-based Dog Food

Our fish-based dog food range is made with high-quality, natural ingredients to support your dog’s health and happiness at every life stage. Fish is a gentle source of protein, ideal for dogs with sensitive stomachs, and naturally rich in omega-3 fatty acids, which promote joint care, brain function, and a healthy coat. Fish is also lower in calories than some other proteins, making it a great diet dog food option, or ideal for feeding for dogs with health conditions such as pancreatitis*.

At Forthglade, we use responsibly sourced varieties of ocean fish and white fish, gently steamed to lock in flavour and nutrients. Whether you're after a complete meal or tasty fish treats for dogs, our fish recipes deliver nourishment in every bite.

We also offer a range of formats, including our award-winning wet dog food, which works brilliantly on its own or alongside our dry recipes. We also offer a range of grain free dog food if your dog has allergies to grains.

So whether your dog prefers grain-free or wholegrain dog food, our fish options offer a naturally delicious choice that’s gentle on tummies and full of goodness.

Salmon & White Fish Dog Food

Our salmon and white fish dog food selections provide variety and nourishment in equal measure. Salmon is rich in essential fatty acids and an excellent source of protein, supporting energy levels and skin health. White fish, being naturally low in fat and easy to digest, is ideal for dogs with dietary sensitivities or those needing a lighter meal.

You’ll find these ingredients featured across our main meals and complementary fish treats for dogs, helping you build a varied, balanced diet your dog will love.

*Always consult your vet regarding your dog's diet when it comes to specific health conditions.
