Can anyone speak to the fact that treats like Happy Hips do not contain enough glucosamine to be of any benefit?
I'm trying to convince someone that his very arthritic dog needs an actual glucosamine supplement; he believes the few daily jerky treats he gives his dog are more than sufficient, because the package says it has however much glucosamine in it.
To me it just makes sense that a processed jerky treat couldn't have enough supplements or nutrients to have any added value. But I'm no nutritionist or veterinarian, nor do I have any data to back up my thoughts on this.
I'm hopeful someone can point to some research that proves this theory.
