Why do dogs pant..? (help)

[CountryWolf07]

Ok! I'm here.. Amy had to get my attention..

Ok update on Rosie - She's still not herself, and it's been three days.. and well, we took her to the vet yesterday, and the vet said that she could have had a fever, but I am pretty sure she had it, and still has it.. her temperature is normal.. her heartbeat is normal.. everything is normal, so..
Sunday was her WORST.. she was shaking, panting, tired, and slept all day, didn't eat anything or drink anything, but yesterday, she ate some meat and rice, about a 1/2 cup, and she'll continue eating that today and for a while until she gets back to normal. She still acts strange, like she'd jump up for no reason, and stare up at the ceiling/lights, which just makes me real nervous.. the vet doesn't know what that could be about.. she still does that.. I just tell her to quit it.... hmm, she has this long blank stare then she'll blink and lay down and sleep.. then she'll jump up and do the same thing.. it's like she's hearing things.. my brothers were joking that we had a ghost around, and pfft, right.. couldn't be that, lol (Amy - ya know the whole story.. )
Rosie's nose is still dry/warm, but today she's a lot better, but she's still just so lazy, although, the vet thinks she's lethargic, and hopefully that'll be just for a while, because she is NEVER lethargic before.. what is so odd, is that, Saturday night, Rosie was just NORMAL!! She just barked, whined, wanted to play with Anna and me, and then Sunday morning, she just becomes so strange.. and still is.. I think she'll be alright.. the vet told us to keep an eye on her since he doesn't know what really happened.. Oh.. she acts AFRAID when she comes inside (from going potty) and heads *straight* to my bedroom, then my mom's bedroom, then back to mine, usually she'll stay on my bed and sleep.. and I'd watch her, and she'd get up and walk to the side of the bed and look out at the window, but if I say something to her, she'll get scared and just head right under the covers and stay there.. see, if I leave, she'll go right out and sit by the side again? Ok Rosie.. please get better soon.. Ok, well, that's the update so far right now, but I'll let y'all know when she gets back to normal!!
