Salmon Broth

Fish processors cook salmon for food and other products. Cooking leaves a flavored liquid alongside the fish solids. Using that liquid as broth gives processors another saleable ingredient.^5,6,8

1. 01 // Source Salmon flesh or parts Salmon supplies the fish material; the ingredient name does not identify the cuts used.
2. 02 // Process Cooked with water Cooking moves soluble fish compounds into the surrounding liquid.
3. 03 // Process Liquid separated The cooking liquid is collected apart from the fish solids.
4. 04 // Output Salmon broth The liquid is added to food for moisture and fish flavor.

1. 01

   Adds recipe moisture

   Broth supplies liquid to wet food and toppers. The water counts toward a dog's intake when the dog eats the food.^1,5

2. 02

   Adds fish flavor

   Cooking transfers fish compounds into liquid. A brand sells the resulting taste as a reason to use broth, but dog preference for salmon broth itself has not been tested.^2,10

3. 03

   Uses a processing stream

   Simmering fish produces broth as a by-product of canned fish production. Broths in general are used in pet food manufacturing, giving processors a use for this cooking liquid.^5,9

How much One disclosed wet dog food lists salmon broth at 25.6% of its recipe; a single formula does not show a typical amount.¹¹

1. Brands say

   Salmon broth adds water to a meal

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   Broth is mostly liquid, so adding it raises a meal's water content, plain arithmetic. A 16-dog, 56-day trial found a different liquid, a nutrient-enriched water, raised total water intake and diluted urine; it did not test broth, so broth's effect on hydration is unproven.^1,5

2. Brands say

   Salmon broth makes picky dogs eat

   Outruns the evidence

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   Dogs preferred a diet containing 10% salmon protein hydrolysate in one feeding test. Hydrolysate is a different ingredient. No opened dog trial tested salmon broth, so its fish flavor does not guarantee better intake.^2,10

3. Brands say

   Its omega-3s improve skin and coat

   Outruns the evidence

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   A 16-dog crossover trial found coat benefits from a marine oil supplement, each millilitre of oil holding 180 mg EPA and 120 mg DHA. No cited salmon-broth analysis gives an EPA or DHA amount, so the oil result cannot be assigned to broth.^3,5

4. Brands say

   Broth provides concentrated salmon nutrients

   Outruns the evidence

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   A brand calls broth a concentrated nutrient source. One measured, defatted fish broth was 10.49% solids and 7.46% protein as poured. It is not salmon broth, so it cannot show the nutrient content of a salmon-broth product.^5,10

5. Owners say

   Salmon broth is safe for fish-allergic dogs

   Outruns the evidence

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   In a fish-allergy study, 27 dogs had reacted to cod challenges. Serum from some cod-reactive dogs also bound salmon proteins, though researchers did not challenge them with salmon. Broth is not an allergy-safe shortcut for a dog with a diagnosed fish trigger.⁴
