Thanks everyone,her back legs went a few weeks ago and she was treated with everything going but they went again suddenly last night,she couldn't move them at all.Got her to the vets and he said he thought he could feel a mass pressing on her spine,we could've tried more medication but he said we were just buying time really so I thought it was kindest to let her go (I feel so guilty though) The vet left me alone with her as she went so I could kiss and stroke her and tell her how much we loved her.So awful going out to just Gabbie this morning
