well... update! i talked to my breeders this weekend, and they agreed, it's probably from the food. i guess his mother has had them all her life as well, and they just switched her to a sensitive stomach formula, which is what we did this weekend! and apparently, this is interesting to know.. someone who had a newfie for 11 years (we can all be so luckY) said that she found out it was the chicken in the food products.. she cut all the chicken, so that is what we plan on doing. his new food is salmon based, and we got rid of the puppy treats that are chicken based (idiot i am! just bought the giant box! and now down the drain).. but got all lamb and rice and fish based ones! hopefully this helps fumble! and maybe some of you too!
