There many causes of joint issues with dogs but for many Glucosamine and Chondroitin are recommended.
Glucosamine is involved in the formation of tendons, skin, bones and ligamentsand maintains the ability of cartilage to hold water and act as a shock absorber.
Chondroitin is responsible for the formation, resilience and repair of cartilage - quite an important ingredient for joint health.
We supply "Joint Aid Granules" and "Dorwest Glucosamine and Chondroitin Tablets". The granules are easy to feed as they are simply sprinkled onto the dog's normal food.
The Joint Aid also includes Collagen, Curcumin, Glutamine, MSM, Antioxidants, Polar Lipids, Beta Glucans, Galactolipids and Vitamin C.
The Dorwest is purely medical grade Glucosamine and Chondroitin.
Based on the manufacturers guides (maintenance doses - not necessarily therapeutic) for a 25Kg dog:-
Joint Aid provides 200mg of Glucosamine and 200mg of Chondroitin (10gms Joint Aid per day)
Dorwest Tablets provide 800mg of Glucosamine and 400mg of Chondroitin (2 Tablets per day)
Arthri-Aid provides 750mg of Glucosamine and 90mg of Chondroitin (in 2 tablets per day)
Sashas Blend provides 317mg of combined Glucosamine and Chondroitin (in 2.27g per day)
Royal Canine Mobility Support provides 325mg combined Glucosamine and Chondroitin (in 325g of food)
Omni-Condro has 1000mg of Glucosamine and 535mg Chondroitin per tablet
Of course we suggest that you discuss any change of regime with your Vet but our recommendation is to feed Applaws (75% Chicken Meat Meal - meat protein is what dogs should have for building up muscles and hence providing muscular support around failing joints), Natural Dog Food (22% British Chicken Meat Meal + 21% Fresh British Chicken) or Burns (20% Chicken Meat Meal) for maintenance without increasing weight plus Joint Aid as a supplement for the joint issues. Note that our food ranges are specifically chosen because they use "Real" meats, contain no wheat, soya, or dairy and certainly no hydrolised or, far worse for restricting the uptake of Calcium and Magnesium, hydrolated protein sources.
Note that because of the high nutrition in all of the foods we supply the manufacturer's feeding guidlines are around 250g per day for the 25Kg dog - compare that to the 325g of Royal Canin and the effect on your wallet!
A very interesting set of calculations have been carried out based on prices at 3rd March 2011 for a labrador with knee displasia:
Using Royal Canin Mobility Support + Omnicondro would cost approximately 90€ per month
Using Burns High Oats + Dorwest Glucosamine & Chondroitin would cost approximatley 50€ per month
