No caring !!!!

My mother took her dog in after being attacked by 3 bigger dogs, the vet basically just stitched the wounds without cleaning them first and a gaping hole was left in the dogs flesh, the vet said that this was done to drain the wound, 3 days later and the dog was getting worse, my mom went for a second opinion only for the other vet to have done a scan and there were two holes in the dogs lungs. the wound that was left untreated was badly infected internally. I find that this is really unexceptable as this dog may loose its life due to poor service and then they aren't shy on charging for these so called services!!!! VERY INHUMANE!!!
