Most dogs with hyperlipidemia have a underlying endocrine disorder, such as diabetes mellitus, hypothyroidism, or Cushing's syndrome, that is responsible for their hyperlipidemia.
However, primary hyperlipidemia or hypertriglyceridemia is also relatively common, especially in Miniature Schnauzers where hyperlipidemia appears to have a genetic basis (1-4). In these patients, administration of fish oils or lipid-lowering agents are sometimes used, but dietary therapy with a low-fat diet remains the primary means of controlling the hyperlipidemia.
What is the Best Commercial Diet to Feed a Dogs with Primary or Secondary Hyperlipidemia?
All of the major pet food companies have low-fat diet on the market. I preferred the Royal Canin Gastrointestinal Low Fat LF™diets (5,6) when I have dogs that needs to be fed a low-fat diet. These formulas are low in dietary fat and are indicated for adult dogs with pancreatitis or hyperlipidemia. Additionally, the formulas are highly digestible, enriched with prebiotics, and contain a precise blend of antioxidants.
Both the dry and canned formulations are extremely low in dietary fat (15.5-15.6% fat calories in either dry or canned formulation) (see Table, below).

In addition to being more effective in controlling hyperlipidemia, most owners find Royal Canin to be more palatable than the Hill's w/d. However, if palatability is an issue with any of these diets, lean protein treats can be added to the prescription diets. These include chunk light canned tuna, low-fat cottage cheese, skinless chicken breast, pork loin, egg white or tilapia.
