OMG Ellie!! What luck you got into the vet today!! Amazing. I've got to tell you, when Delilah hurt herself back several months ago, she was acting just like Sparky is. She is normally a very peppy dog for her age(she's 10 now). When she jurt herself after her bath the other day, she was right back to acting out of it, lethargic, uninterested in anything, etc.

I can't give her aspirin because it doesn't agree with her. She got sick with it. They gave me Duramaxx(I think that's it). Another time she got Rimadyl(I think). Both of those made her act completely different. Once she got over the pain, I think she was back to normal. This could be why Sparky is "coming and going" with the limping. Sometimes the aspirin may be kicking in and other times, not so much. This all sounds so familiar. I think Sparky is going to be ok from the sounds of it. I sure hope so.

Sorry I'm not sure about the medicine names. If I wasn't so lazy I would go look. If you want to know, PM me and I'll find out for you.

Feel better Sparky!!! I think I know how you feel, sweetheart!!!
