So I had to give my pitbull puppy away in January. I ask the new owner how she’s doing every once in a while. I asked him again yesterday he told me he forgot to give her her vaccinations and shots so she’s been really sick for weeks , I suggested he take her to the vet . I asked him what the vet said and he told me the vet said it was too late so she died. I’m so sad and so angry . Is this negligence?
