we did take her to the vet & they did have a name for the growing pains but i can't pronounce or spell it. 1st they thought something was wrong with her lower back or pelvis & did xrays & found nothing. the pain med.s they gave her were not enough to keep her comfortable & it seemed to get worse so i brought her back to the vet & she was examined by another vet & she thought she may have fractured a growth plate someplace that it wasn't showing up on xrays, she said sometimes they can't see it until it heals which could take up to 6 weeks so the vet gave her some tramadol 25mg to take with the previcox for pain. they really don't know for sure what is wrong. I wondered if this could have anything to do with her getting into the composte bucket for the garden which had coffee grinds,potatoe skins and egg shells in it? Any ideas? This is crazy having to carry this 35lb lab outside everytime she has to go potty. please help her..
