For the past two nights Riley has had to go outside 2-3 times. Each time she had pretty formed stools but they looked very slimy - almost as if they were covered in colorless mucus. After the first night, I just watched her most of the day and she was fine so I thought what ever it was had passed. However, then 2 times out last night, and then this morning Oliver had a very slimy, mucusy stool also. For both dogs, the stool is formed, not diarrhea, but it is softer than normal. I took stool samples into the vet today but was just curious if anyone knew anything about what this might be. Appetites and energy level are fine for both of them. And Oliver knew I was taking Riley out last night at 1 and 4 a.m. and he didn't even attempt to get up to go, so his is not as urgent as her feeling is. Any thoughts?
