We recently adoped a second puppy, a 10 wk old Chihuahua/Terrier Mix, Maggie Moo. On Sunday, Apr. 15, 2012, we were on vacation. Maggie had a big day on the beach and had been sleeping for the past 3 hours. We went to wake her up to notice that she was unresponsive. It took quite a while before she came to. Monday, we took her in to see O'Donnell and asked for her to do some bloodwork, to give a baseline. She refused and said it was normal. The next Saturday, Apr. 21, we brought her in for her vaccine. O'Donnell gave her the injection, but pushed needle in too far that it came out the other side of Maggie and the serium shot across the room. Tuesday, Apr. 24 it rained all night. Wed. morning, she went out to potty, put her on the yard leash, and shortly let her back in. She was acting normal. Before long, she looked lethargic, and she puked and had diarrhea. I took her in to see O'Donnell at 9:30a along with samples of the fluids, of which she ignored. I came back at 1:30p to check on her, they had not gotten to her yet, but gave her an anti-nausea shot because she continued to puke. I asked them to do some blood work. 4:30p, they called and said she is ready to go home. Her ACL (liver enzyme) was 1736, should be 110, she said it was "slightly elevated" and was more worried about her sugar 32/100. She said to give her some food and bring her in tomorrow if she doesnt get better. Maggie died that evening from liver failure by eating a mushroom and not properly treated.
