Macy is a new tripawd.  Her surgery was March 17, 2009 for a front left amputation of a deformed leg.  She is approx. 7 months old pit bull and weighs 36 lbs.  I rescued her after she was found left in a crate, in below freezing temps, on a back deck after the scumbags moved out of the house.  It is believed she lived her first 6 months of life in her crate. 

When her deformed leg was removed 9 days ago you would have never known she had surgery.  Her activity level never changed from before surgery.  She was so full of life and energetic until 3 days ago.  She started laying around and sleeping more and seemed gimpy in her rear area.  She can't get on the couch now and after a short walk she just collapses.  She also has lost her appetite. 

I took her to the vet yesterday and she had no infection and no temp…he said that he tought she has hurt the hip/back area by too much activity.  He took her off her anti-inflammatory thinking that was causing the loss of appetite.  He said to limit her activity for a few days and see if she don't perk up. 

This morning she came out of her crate happy, went out and used the bathroom, came in the house and laid down and went to sleep.  I cooked her some ground beef and she ate that and drank a little water then back to sleep.  Sometimes she cries like she is in pain.  She perks up for only a minute when someone new comes in but then is back down.  I'm considering taking her back today for IV fluids but was wondering, from people who have been through this, if this is normal behavior?  Has it finally caught up with her and she just needs to sleep or should I be concerned about something else?
