I notice that some dog food contain Glucosamine and Chondroitin. I know that it is good for joints so have often bought dog food containing it. I am now feeding cold pressed food but the brand I am using does not have it as an ingredient. I have seen other brands that do include it as an additive.
Is it a good thing to have Glucosamine and Chondroitin in the dog’s food rather than buy it as a supplement when the dog becomes a senior?
I think it is a matter of opinion. Personally I would prefer it not to be added so that the pet owner can administer the supplement at the correct dose should they wish. I have read that it is important to obtain a good quality product - not all preparations are equal. Bone broth is said to be a good, natural source of glucosamine. It’s also useful for fussy dogs as it can be sprinkled over food.
I agree with Dottie. I add eggshell membrane a few times a week.
