My dog is a dachshund/yorkie mix. She is usually very active. This afternoon, she was outside and I heard her bark so I went to check on her. She was laying in the grass and looked fine. I went back inside and she barked again, I went out and she wouldn't get up. I lifted up her tie-out and she jumped up and ran skittishly to and up the stairs. Once we went inside she ran and dove onto the floor, rubbing her face on the ground. She was also constantly licking an area near her tummy. She finally laid on the couch and was very tired. I was worried and wanted to see if she was hurt somewhere, so I tried to get her to move. It was really difficult to get to her move at all and when she did, it was skittish and fast. I was able to check the area she was licking and pushed on it and she didn't whine or cry at all. But she has not moved places in about an hour. I am not sure why happened outside, originally I though maybe she was stung by a bee, but I don't see any bites and I don't think that makes dogs lethargic. Then I was reading about algae poisoning. There is some algae on our driveway that she sometimes drinks water from, but she's never reacted like this. She also through up this morning and had been eating grass yesterday.
