Fish is an excellent source of protein rich in Omega-3 fatty acids, which have health benefits like antioxidants and anti-inflammatory properties, aiding your dog’s joints and all round mobility. Fish is also known to have beneficial properties for your dog or cat's skin, fur, heart, and brain. It is relatively low in saturated fats, making it a brilliant source of nutrition alongside other meat proteins. The best two Omega-3 fatty acids for dogs and cats, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are found in the oils of fatty fish.
Feeding small oily fish like sardines, smelt, herring, and mackerel provide the necessary amount of Omega-3. Fish should be the last protein to be fed in the transition, followed by eggs. Carnivores, like cats and dogs, are high-density lipoprotein mammals, meaning they can tolerate high dietary fat concentrations but even then it should be introduced slowly to begin with or you might see it reappear out the other end!
It is recommended that dogs need 300mg of Omega-3 EPA and DHA per 30 lbs (13.6 kg) of body weight. Feed total weight of fish, based on weight of cat or dog.
Amounts to feed per week:
• Small dogs and cats - 33g (1.2 oz) of small oily fish per 10 lbs (4.5kg) of body weight
• Medium to large dogs - 100g (3.5 oz) of small oily fish per 30 lbs (13.6 kg) of body weight
