Lucky Lucy

We had a scare with our dog last night. We have 2 dogs- Lucy and Paris. My Dad for some reason refuses to call Lucy "Lucy" but instead calls her "Lucky".... he loves her. Lucy is a 13 year old Bichon Frise, and Paris is a 4 year old Yorkie. Lucy is pretty much blind and deaf, but I attribute part of her seemingly happy life to Paris. It has not always been this way. When Paris came along, Lucy was NOT happy. Lucy saw her as an outsider and spent the first few weeks of her sister's existence growling at this intruder. But after Paris pretty much claimed her stake as the princess of the dog world in our house ( as Yorkies do) , Lucy has bowed down to her and completely enjoys and begs for her company. If Lucy is outside without Paris, she whines at the door until we let Paris go out with her so Lucy can sniff and smell every step Paris takes. Well yesterday Lucy had vomited a few times and did not finish her food which is completely out of character for her. I didn't think a whole lot about it because she has had her share of bugs over the years that she quickly gets over. But last night my 15 year old called my attention to her circling and circling after being let in from outside. She couldn't walk a straight line and with her head leaning to the left she acted like she was chasing her tail, but it wasn't funny like that. I saw that her eyes were spastically twitching from side to side and she was out of balance and disoriented. Thanks to the internet, we found her exact symptoms under "Vesitibular Disease/Syndrome". The range of concern varied from a mild (will correct itself in a few weeks) to severe ( cancer, tumor, bad news). We took her this morning to find out that her case is mild compared to others who can't get up on all fours, and her blood work is great. The vet said a neuron in her brain most likely misfired, or missed it's connection (or something like that) and will take some time to recover, but she should be ok. They are keeping her until she can keep food down, but we are hopeful. In the meantime we know that Paris, who misses her sister, is certain (as she saw me throught the window carry her to the car) that she is on all expense paid vacation filled with endless treats, walks, and attention, but is starting to wonder.
