Here is the details from the dog warden who picked her up:
SBT x Mastiff (?) bitch white with tan on ears and tiny tan patch on tail med size & build short smooth coat full tail no collar no tag no chip approx. 3-4 yrs old collected from Barnford Park in Oldbury where she was cowering between two fences, in a space about 18" wide. She had one of the worst injuries to her neck, that I have ever seen. A gash about 6" long by 2" wide by 1" deep ran from the back of her right ear, down the neck to level with the jaw bone. There was also a split about 2.5" long in the back of the ear itself and a "V" shaped piece of the end of the ear itself was missing. There were many old scars from "puncture wounds" in many locations mainly on the front legs and head. The Vet., tried to get her to walk, but found a problem with her back right leg. He said there seemed to be almost no sensation in the leg at all.
The dog will be treated at the RSPCA Hospital in Barnes Hill, and if she recovers and is fit to be rehomed, they will contact us to arrange this.
At the moment, the Vet., said that the ear is so infected, and riddled with fly strike, that it may well necrate, and literally drop off. The leg problem could just be an old break, or could be something more serious, and need to be amputated. The open wound on the neck would need to be left open for a while "to see what drops off, and what regenerates". She was given three injections, one was an antibiotic, one was Morphine, and the other was a sort of Aspirin substitute. He said they would anaesthetise her later tonight, and get a better look at the situation after they had been able to clean things up a bit, and investigate the leg problem further. He suggested that I ring them some time tomorrow and he would know more about her condition, and be able to give a better prognosis.
Throughout all this "messing her about", she never once growled or snarled at any of us. I thought she curled her lip a little when he went to look at her teeth, but it was over so quickly, that I am not sure about this at all.
