Bacon

Meat processors cure pork bellies to preserve them and develop flavor. Salt is applied dry or injected in brine. A common route then cooks or smokes the belly and chills it before slicing.^5,6,10

1. 01 // Source Pork belly A belly cut supplies the layers of meat and fat that become bacon.
2. 02 // Process Salt cure Processors coat the belly with curing salt or inject a brine; nitrite is often included.
3. 03 // Process Heat or smoke Cured belly may be cooked or hot smoked, then chilled before slicing.
4. 04 // Output Bacon The cured pork belly is bacon, a named ingredient on dog treat labels; the label does not disclose its supplier or cut size.

1. 01

   Adds a meaty draw

   In paired bait tests, bacon flavor attracted dogs, though another test favored ordinary dog food flavor. These tests say nothing about how much real bacon improves a meal.^1,2

2. 02

   Adds fat and energy

   The unprepared bacon entry is about 70% fat on a dry basis. Any added bacon therefore brings calories along with its cured meat flavor.^4,6

3. 03

   Sells a familiar name

   A major treat brand calls out real bacon on its package while listing bacon after pork, grains and water. The label gives no bacon percentage.^5,10

How much A pet treat label names bacon without stating its percentage; the dog trials tested flavored baits, not measured bacon in complete meals.^1,2,5,10

1. Critics say

   Bacon is mostly fat on a dry basis

   Evidence

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

   One USDA unprepared bacon entry works out to 70% fat and 26% protein on a dry basis. Bacon supplies energy and some protein, but the protein figure does not make it lean meat.⁴

2. Brands say

   Bacon flavor makes dogs want to eat

   Outruns the evidence

   Evidence

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

   In a 26-dog paired bait test, bacon flavor beat each alternative. In a 13-dog test, ordinary dog food flavor ranked first. Neither study measured real bacon added to a complete meal.^1,2

3. Brands say

   Bacon is a useful protein source

   Outruns the evidence

   Evidence

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

   One unprepared bacon entry contains about 26% protein on a dry basis, against 70% fat. Ingredient lists give no bacon percentage, and the cited label, treat package and AAFCO guidance give no figure for how much protein bacon actually contributes once it sits low on a recipe.^4,5,10

4. Owners say

   Bacon always causes pancreatitis

   Outruns the evidence

   Evidence

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

   Merck recommends less than 20 g fat per 1,000 kcal during treatment for canine pancreatitis. Fat-heavy bacon is a poor extra for those dogs, but the cited guidance does not show every dog becomes ill after eating it.^4,7

5. Owners say

   Any bacon causes salt poisoning

   Outruns the evidence

   Evidence

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

   The USDA entry yields 14.1 g sodium per kg dry bacon. Merck links salt poisoning to excess intake, especially with limited water. A bacon listing does not tell you that a dog received a toxic dose.^4,8
