Hi yellow lab,generally higher calorie content food is preferred but tumor cells are much likely to use fat for energy. It is recommended that food should be 25-40 % fat on a dry matter basis. For them carbohydrates food should be less than that 25% of the food.
I suggest high level of protein and fats combined with lower levels of carbohydrates are most beneficial. Going grain free is the best option for the diet. Make sure you read the ingredient label and it will be good while the two ingredients are some type of meat. choose different brand that is very important.
BARF diet is best for the yellow lab. It contains biologically appropriated raw foods and also 75% meat and 25% fruit/veggies.
