I took Sadie to the vet this morning because I couldn't wait till Monday in case she got worse. The vet said her heart, lungs and all other organs look good. She checked her hips out since I told her Sadie has not been jumping like normal. She said she seems to have some pain in her hip area but she is bearing weight on it like normal, she just won't jump. She gave her an anti-inflammatory shot and some Rimadyl. She told me if she gets worse or doesn't improve to bring her back in and they would x-ray her. She also checked her glands and she said they were about 2/3 full, not bad, and she went ahead and cleaned them out as well. She has been better today, running around and playing. Looks like the shot has helped her. I'm also gonna cut back on her food and treats as she is a little overweight and this might be contributing to her soft tissue injury. The vet said she might have hurt it jumping before. Anyways, I'm going to try and get her slimmed down some so she is not carrying so much weight and hopefully to avoid her straining her muscles. Thanks everyone for the advice and comments.
