Question

I have a 6 year old female Rottweiler. She started with loose stools two days ago, today being the third day. I found her "grazing" in our garden one day last week. As the gardening season is finished, I am not sure what she got into. Nothing poisonous I do not believe. There was some vegetables we were letting "compost". I have been giving her cooked rice with her dog food for two days. Today, I started just plain rice....no dog food and have not allowed her to run free in the yard so she has not been in the garden. She is drinking double the normal amount of water, so I'm sure she is not dehydrating. She is not weak and is able to let me know when she needs to go out. Should I continue the "rice only" treatment, or is there something else I can do to help her.
