Manganese Deficiency Contributes to CCL Illness in Canines


Opposite to standard perception, most cranial cruciate ligament issues in canine don’t come up from acute accidents. A scarcity of manganese within the weight loss program is a serious contributor.

Cranial cruciate ligament (CCL) illness arises all too ceaselessly in our canine. It’s a quite common cause for hind leg lameness, ache, and arthritis of the knee, and could be fairly critical and debilitating. Though it’s pure to suppose all CCL issues in canine are brought on by sudden or acute harm, that isn’t the case. Diet additionally performs a task — particularly, manganese deficiency could be a key contributor.


Canines are supposed to dash upstairs, sometimes slide throughout flooring, and repeatedly soar on and off issues, and not tear a ligament. But most veterinarians frequently see sufferers who have been simply dwelling their regular lives with no trauma, however developed CCL illness. This isn’t how wholesome our bodies are designed to reply to an lively life-style.

I seen a few years in the past that CCL issues have been the commonest mushy tissue accidents I used to be seeing in my apply. Since only a few of those accidents have been brought on by trauma substantial sufficient to warrant a rupture, I went digging for clues and located that my CCL sufferers fell into 4 totally different classes:

  1. Canines that skilled a traumatic harm (what I name the “Mack Truck” state of affairs).
  2. Giant or big breed canine, or those who have been obese. Alternatively, the situation had a genetic element, or the canine have been over-vaccinated, or spayed/neutered versus sterilized (through ovary-sparing spays, which preserve well being hormones however stop being pregnant).
  3. These consuming poor high quality processed meals to which equally poor high quality artificial nutritional vitamins and minerals had been added to satisfy AAFCO minimal nutrient necessities.
  4. Canines consuming selfmade “prey mannequin” diets that have been nutritionally imbalanced.

Apparently, the overwhelming majority of canine I used to be seeing with CCL harm have been lively, wholesome animals that had been sterilized however not de-sexed. They weren’t over-vaccinated, they usually weren’t obese. However many consumers have been feeding prey mannequin selfmade diets (80% meat, 10% bone, 10% organs) that weren’t nutritionally balanced. This made me suspect insufficient diet as a possible trigger for many CCL accidents in my sufferers.


I got here up with one recurring issue associated to connective tissue resiliency: the dietary consumption of manganese (Mn). Manganese is required for wholesome, sturdy ligament improvement and upkeep. A canine’s manganese necessities are excessive, and meals sources differ as to the quantity of manganese they include.

Poor high quality processed canine meals don’t include sufficient manganese. Amongst those that home-prepare their canine’ meals, many don’t comply with recipes. Most prey mannequin feeders mistakenly assume that the number of free vary, natural meat, bone and organ blends they feed their canine include all of the minerals they want. Nevertheless, the sheer quantity of non-traumatic CCL tears that veterinarians are seeing in prey model-fed canine tells a distinct story.


The place does manganese come from within the ancestral canine weight loss program? Minute quantities come from meat, liver and bone, however these sources don’t present almost sufficient manganese to satisfy a canine’s day by day necessities, which is why so many canine turn into poor. The richest sources of manganese truly come from the animal components none of us use — primarily hair, feathers and wool.

The wild canine’s ancestral weight loss program and life-style offered an abundance of alternatives for consuming manganese, however that is merely not the case for domesticated canine. The ancestral weight loss program offered, on common, 3.1 mg of manganese per 1,000 kcal (energy) — a really ligament-supportive weight loss program. In distinction, AAFCO minimal manganese necessities are 1.8 mg per 1,000 kcal of meals. That is roughly 50% of the manganese the ancestral weight loss program offered.


As an alternative of feeding extra nutritionally compete ancestral diets, many individuals give their canine selfmade prey mannequin diets as an alternative. A prey mannequin weight loss program of 80/10/10 lean beef provides 0.22 mg Mn per 1,000 kcal (and that determine is even decrease if the meat is lower than 90% lean). An 80/10/10 prey mannequin weight loss program utilizing hen provides 0.12 mg Mn per 1,000 kcal. That is much more poor in manganese than AAFCO’s too-low really useful minimums present in processed meals.

These figures spotlight two essential issues:

  1. The distinction between supplying simply sufficient vitamins to outlive (AAFCO requirements) versus supplying the vitamins wanted to thrive (ancestral weight loss program diet parameters) means lots of canine are ending up on the veterinary orthopedic surgeon’s workplace.
  2. Prey mannequin feeders — those that are spending some huge cash feeding unbalanced, recent meals diets to canine with torn cruciate ligaments — must reassess how nicely their “steadiness over time” method is actually working. Actually, what number of prey mannequin feeders constantly add lambs’ wool to their canine’ bowls?


My advice to assist your canine keep away from CCL accidents is straightforward — don’t guess at his weight loss program.

  • When you’re feeding selfmade, make sure that his meals meet the ancestral weight loss program necessities for optimum nutrient consumption (not only for manganese, however for all vitamins). Observe a recipe that offers you the quantity of manganese per serving or 1,000 kcal.
  • There are additionally premium meals obtainable which are formulated with the extra demanding ancestral weight loss program requirements versus AAFCO’s poor minimums. Name the corporate and ask what formulation pointers they comply with (AAFCO or ancestral), or how a lot manganese (per 1,000 kcal) is of their meals.
  • Complement as needed with complete meals or a complement to satisfy manganese necessities. Examples of complete meals that include manganese embody uncooked spinach, uncooked blue mussel, and uncooked blackberries. Though you couldn’t feed these meals in excessive sufficient concentrations to satisfy your canine’s manganese necessities, including them in small quantities could be useful.
  • It’s additionally essential to maintain your canine in good bodily form, and keep away from over-vaccination by asking your vet about titer testing.
  • Preserve your canine intact by choosing an ovary-sparing spay or vasectomy when doable.

In case your canine is consuming a ligament-supportive weight loss program, he shouldn’t develop degenerative cruciate harm until he will get right into a critical accident. In case your canine has sustained a CCL harm, companion with a canine rehabilitation facility in addition to a holistic veterinarian who can supply him the very best likelihood of restoration.
