I have a 2 year old, female, Portuguese Water Dog who is currently in the end of her third heat cycle. Yesterday after returning home we found that she had had diarrhea in her crate, she's NEVER done that. When we took her outside, she had another 2 bouts of it. I homecooked her some rice and chicken and she ate 1 cup last night along with one piece of bread and she had one cup this morning with a piece of bread. She has yet to have another bowel movement. Her last one was around 8pm last night. She seems to be acting pretty normal, running around like a nut in the yard and her nose is cool and moist. Should I be concerned??? Please reassure me!
