My dog has very bad gas

[critter crazy]

Most often times, bad gas is related to the food. Since you have stated you have fed the dog, science diet and Purina, I would try a better dog food. neither of theose are good quality kibble. I would try aomething like Orijen, Merrick, Canidae ect... I am sure there are others as well.

Sometimes treats can cause bad gas. Anything from pig ears, to sausage type treats, to people food. Depends on the animal. Might want to check what kind of treats the dog is getting, including checking with others in your house or your neighbors in case someone has been sneaking the dog some treats.

Yes, unless his teeth are bad - unlikely in a young pup, it probably has to do with the food he is eating. Try a simple food, like a Lamb and Rice version - switch over gradually, and see if it makes a difference.

Mabye he needs some Pepto?

Yes I would try a higher quality food, that doesn't have corn fillers. Science diet and Purina aren't very high quality. Sorry

I suggest cannidae, innova, merrick, solid gold, wellness, or chicken soup for the dog lover's soul.

Your puppy sounds adorable!
