Oh I'm so sorry for Cindy - it doesn't sound good. Is it possible she really was hit yesterday? I haven't read the rest of the posts yet, but if she's not moving today, I think you might want to have a vet look at her.
No she didn't get hit. She is a lab (about 14 y/o) and our Dalmation broke her hip several years ago. She was left with arthritis. She can't leap and fly like she use to and has some muscle wasting but most of the time she's happy and funtionable. She limps when the weather bad but hey so do I:') Occ, maybe twice a year her back legs give out. It isn't painful to touch but she has to sleep with the lower back on her side but laying on her front trunk and can't put her head down. I log rolled her hips and made her a pillow to prop her head and put hot packs on and she finally went to sleep. The medicine has kicked in and she's better now. As for me, my shoulder aching. This month is Texas older citizen month. I saw a saying that "how old would you be if you didn't know how old you were?" and I was thinking around 32. Must have been a good year. Anyway, I forget or ignore my limitations sometimes too and should not have picked a 75 pound dog up under her front legs and carried her to the bedroom.
