I started to switch my almost 7 month old puppy to adult food and all of a sudden she has terrible gas! I started with 1 3/4 cup puppy to 1/4 cup adult. Did this for 5 days with no problems then I went to 1 1/2 cup puppy to 1/2 cup adult and really bad gas started! Her first poop in the morning is normal but after she eats it is a little soft. It is still formed just soft. She has always been on pro plan chicken and rice lbp. I stayed with pro plan but adult instead of puppy. Is this normal until she adjusts? Should I continue or start over again? Please any advice would be greatly appreciated!
