. i have a lab mix about 8 or 9 years old. i came home the other day and she wasnt actin right almost like she was scared of something. well i kept watching her and she has been laying around like she doesnt feel good and acts very stiff when shes walking or getting on the porch. i though maybe she had ate something bad at first, but today i was rubbing her and sort of pressing on certain spots on her to see if i could find what was bothering her i finally come across her back i guess it would be her lower back or hips, its right where her legs connect to her back, its a little puffy back there and she doesnt want me to touch it. do u think it could be a pulled muscle from wrestling with other dogs or something else? is there anything i can do to ease the pain. and also will this eventually go away if she rests? is there a pain reliever u can give dogs? thanks for the help
