First, I make my own dog food, and anyone who attempts this knows how complicated it is. So maybe I shouldn't have purchased something that was an additive for commercial dog foods. However, I felt just in case I was missing something this would be a great safety net.
I really needed to know precisely how much calcium there is in each scoop. I use a bone meal calcium with phosphorous and magnesium in my recipes and I want to subtract the appropriate amount depending on the calcium in the Nutra Thrive.
I called Nutra Thrive (Ultimate Pet Nutrition) twice and they are not able to give that information, it isn't available to the reps you talk to on the phone. I was given a weight, but it seemed to be the weight of the composite (not calcium alone) and was very high. I told them that I didn't think that was right, it was much higher than recommended, and it was probably for the whole scoop and not for the calcium in the scoop. They couldn't help me any more than that.
FYI, a dog needs 50 mg calcium per kilogram of body weight. A kilogram = 2.2 pounds. So a 20-pound dog needs 450 mg calcium per day.
The first rep I talked to said Nutra Thrive has 3.8 GRAMS, not milligrams, the second said 1.8 GRAMS per scoop.
1 gram = 1000 mgs, so you can see how extremely high one scoop of Nutra Thrive would be if the reps were correct. I'm going to assume that they aren't correct.
Based on that conversation I ended my subscription. I told them that unless I could get a printout of the specific nutrition content, I didn't want it.
I'm not saying this isn't a great product, and dogs on commercial food wouldn't benefit from it. I'm extremely cautious and with senior dogs, I'm not going to take any chances.
Bottom Line: No, I would not recommend this to a friend
