Hi Everyone! My name is Allie and I'm new to this site. My Havanese, Lola suffered a back injury this morning. I believe she jumped off the bed and landed wrong which has resulted in a pulled muscle (at least thats what my vet seems to think it is). From what I read online, she has classic signs. I'm worried because she got a cortisone shot this morning and it seems to have gotten worse. She's really not walking unless I take her outside but when I try to pick her up to take her outside she freaks. Has anyone else experienced this? How long does it take for the shot to start working? I'm a complete mess, I love her so much. Thanks.
