Oh my gosh, 3 days?!?!?! Yes we would be at the vets for sure in that case! Scary! Well I have to say my boys have been extra gassy lately also so I dont know what is going on there, maybe it is all tied in like Jillh10 said, inflamed bowels? I am still switching foods over from the avoderm to fromm and it is too slow for my taste but I had a good amount left and was anxious to start the switch. They are just staying at 2/1 of new to old right now and have been there for a while, till we get rid of the old and can switch fully. Cant imagine the switch would do this unless it is the fromm making them so gassy? Then again I have tried to cut out most dog treats and give more veggies so maybe the lima beans and green beans are overkill? Not that I have given them all that much, not even everyday do they get them. Hmm.... lets just hope tomorrow we dont see any blood and all is back to normal.
