Way to prevent digestive sensitivities?
This is probably a really silly question, but I was curious as to whether or not there is a way to prevent stomach/digestive sensitivities in dogs? It seems like pretty well everyone but me can feed their dogs whatever without them getting sick, but if mine have a small morsel of anything, we have vomiting or diarrhea for a day or two. I think a lot of it is just them, but I also wonder if it's because I didn't give them anything really out of the ordinary as puppies? Just training treats and their kibble. The Dobermans are worse than Dance, but even she sometimes has issues. The Dobes had major issues even as puppies with kibble though, so I was afraid to give them anything else. It took forever to find something that they could eat and do well on.
Do you think some dogs really are just ultra sensitive to different foods? Or is it something you can try to deter by giving them all sorts of different things when they're young? I've never really thought about it before and was wondering what others' thoughts were on the matter. It'd be nice to have a dog one day that I don't have to worry about many tummy upsets with, and if there is something I can do to make that happen, that'd be even better.
