Hello everyone ! I am new to this site and also a new mommy to my yorkie, Mya

She is 16 weeks old. Unfortunately my first post isnt the best topic. Mya has diaherra. Today i switched her wet food. Her dry food is Blue Buffalo and her previous breeder gave her a healthy wet food (not sure of the name).
Today i bought her DRY blue buffalo and WET blue buffalo (beef stew). She munched it all up. I know that the transition of foods should be done slowly yet since it was the same brand and only WET food i didnt think it would affect her. She did have loose stools before i fed this to her but now its diaherra

Im not sure what the cause could be. Im very paranoid and want to make sure she is okay. Im not sure if this is urgent enough to take her to the vet right away. She is acting normal, drinking and eating.
I have read about feeding her white rice which is suppose to help. So i will be sure to do that in the morning. Also i was thinking if i should just feed her DRY food for now and see if her stool hardens ???

I really appreciate any suggestions or comments. Thanks
