I want to thank all of you that replied to this. I always learns o much from all of you. I have been through this with Missy before, about once a year-year and a half she gets this way. It was in the 70s here this weekend and that is the reason I asked about the crockpot. I usually do cook it on the stove but I live in a mobile home and all I have to do is turn the stove on and it heats up in here until it is almost unbearable.
My Missy does seem better today. I will play it by the day, we may still wind up at the vet. I knew dogs couldn't have grapes (she loves them too) I had no idea about onions though. She isn't picky about her eating and she loves chicken and rice. So far so good today.
Thanks so vey much everyone.
