Dogs' bodies, like many animals', produce their own vitamin C (humans are something of an oddity in (at least) this regard, as we do not produce our own).
For a long time, veterinary scientists therefore felt it was entirely unnecessary to supplement dogs' vitamin C intake. However, this view is beginning to change.
Vitamin C can help dogs in similar ways to humans - it bolsters their immune systems, and helps them recover more quickly from illnesses, such as kennel cough.
Vitamin C also helps rebuild collagen, the vital joint material, and this is where it helps dogs with joint problems such as hip dysplasia.
Dogs' natural production of vitamin C clocks in at around 18mg per day, but supplementation can kick this up to sgnificantly higher levels - without ill effect - in order to help dogs with joint problems or other illnesses.
Ester-C is a different - and superior - form of vitamin C. It is considered superior due to the way its molecular structure allows for more efficient, slower absorbtion. Additionally, it does not produce the acidity which comes with vitamin C.
Ester-C can help dogs with:>hip dysplasia
Dosage:We researched dosage levels extensively before supplementing our own dogs' diets with Ester-C, and you will want to do the same. Our research concluded that the side effect of overdosing Ester-C is diarrhea.
The dosage will depend on what symptoms or illnesses your dog is exhibiting. A maintenance dose is around 500mg per 15kg of dog, but for a dog with hip dysplasia to get the full benefit this can be increased to as much as can be tolerated before the onset of diarrhea. Start with a maintenance dose, increase it by 500mg a day until your dog experiences diarrhea, then reduce by one level (500mg).
For the most effective absorption, it is best to split the dosage across several intakes each day.
There is no need to look for Ester-C which is specially formulated for dogs. The 'human' version is the same thing, and will work equally effectively. A perfectly healthy dog probably has no need of supplemented Ester-C.
