Well, I'm hearing a whisper now, that the same problem isn't manifesting in Europe.
The theory of the whisperer, is that nutrition is added here by amount of food. So, let's go with the standard 1,000 calories worth of food.
Your dog then gets a certain amount of taurine, etc. per 1,000 calories.
The point made was: what if your dog is too small, or too inactive, to eat that amount of food? Wouldn't their nutrition then suffer, because they aren't getting the minimum?
The system in Europe is, apparently, different. Taking into account activity levels, aka less food, etc.
I don't know, this person could be on the wrong track, but it got me thinking...should we be supplementing our dogs' diets with a good multi-vitamin/mineral etc.?
I've been giving one for many years, on and off, beginning in the 70's, and I've not had problems with it. I've always felt that their supplements, vitamins, oils, etc. have made them healthier, longer lived, and more handsome - with shiny coats, bright eyes, etc.
So, if your dog eats less that a certain amount of food because of age, inactivity, or size, maybe looking into a good supplement wouldn't be a bad idea? I'm sure that you and your vet can look at the food that your dog eats, how much they consume, and how much is in the supplement that you choose, and come up with a healthy dose. Though, I supplement young, active, larger dogs, too.
Just something that I wanted to share. Food for thought, I guess you'd say.
