Glenda, how right you are that everyone has different experinces and what works for one will totally fail for another. Take peanut butter. My boys loved it, They (and Jerry) probably ate one million six hundred thousdand and four peanut butter/jelly, peanutbutter/banana sandwiches. (I made all those sandwiches, love peanut butter on toast, but have never tasted a PB/jelly, PB/banana sandwich.

They never had one iota of problems with all that peanut butter. Yet there are those that will will have severe reaction, some even die, if they eat one bit of PB or anything with peanuts or peanut oil in it.
We eat tons of shrimp, clams, crabs etc and no problem. Others have horrible reactions to any kind of shell critters, shrimp, etc. When I was a teen I had to watch the amount of chocolate I ate because my face would break out if I over did. Today I can eat all tahe chocolate I want to and have no problem with my face, just my waist LOL. Some kids can eat a little sugar and they are bouncing off the ceiling. Others can eat a lot of sugar (my boys) and go take a nap.
When I tried Buck on food I thought better than Purina it didn't work--he threw it up every time. No more experimenting around for me so long as my dogs stay plenty healthy on purina. In the future if I get a dog and purina does not do the job for him it is doing for my dogs today, you can bet your last dollar I will look until I find what works for him, be it week old road kill, Ol Roy, or TO..
I am not the same trusting, naive person I use to be. I am skeptical of "studies" that "prove" Brand X ( of anything) is better than Brand Y because Brand Y will come out with a study "proving" it is better than Brand X. Expert A says Brand 1 is no good, it contains, etc, etc, etc, and that is bad. Brand 2 studies show it is much better. Then along comes Expert B and says "Expert A doesn't know what he is talking about. Studies have proved that etc, etc, etc is needed and Brand 2 does not conatin all these things. Brand 1 is best". Then along comes Expert C and says "They are both wrong. You really need blah, blah blah and Brands 1 and 2 do not contain them. You should use Brand 3."
Okay, here are three experts and each has his/her own opinon. I have read some of the studies and i do not like the wording like "indicates", "may", etc.
Let me tell you about one study. I just found this out recently when i read the entire transcript of the hearing held Jan. 31, 2005 to try to get Proheart6 back on the market. Fort Dodge had been saying how their field trial (study) using 280 proved how safe PH6 was. Well, at the hearing the panel asked about the 12 dogs of the 280 that either died or had to be put to sleep. According to Fort Dodge "some were hit by cars, some lost in hunting accidents, some 'ate' antifreeze, various things. Apparently the panel was not quite satisfied with that answer and finally FD did admit two had reactions and died (but they were older dogs) and one had a reaction and couldn't recover (but he was an underwwight dog) and ended up being put to sleep. So even at that, 3 of 280 died due to ProHeart6 and that is a little over 1%. That does not sound like much, but that is a little over 1 dog out of every one hundred. Consider how many dogs are on this board and think about one out of every 100 having a reaction and dying.........that is TOOOOOOO many.
But the point is, the entire story was not told to begin with. It was claimed to be safe and people like me were lulled into believing it was safe and it was not. But "STUDIES SHOWED IT WAS SAFE." This is just one reason why I no longer depend on studies, but on my own experience. I think 99.9% of studies are done by the makers, manufactures, or people with interest in the products and are going to tweak the results in their favor, and this goes for not only dog food companies, but ALL companies.
To me, people are about dog food/feeding style like they are about religion. There are all kinds of religions and in most cases, each one thinks they are the best, the most correct, etc. and some even believe they are the ONLY right one. I do not believe that any one is the ONLY right one and i do not believe any one dog food is the ONLY right one and the any style of feeding is the ONLY right one. Gee, got long winded, didn't I. Happens when you get old.
