Im on another forum, non dog, and a member there says he goes to the same vet as that dogs owner. on that site he said this about the dog...
Female bull terrier named Inga. Porcupine is dead, these pictures are at the vets, just before the long costly removal period. Dog is doing OK, is on antibiotics, and tongue is really swollen and still can't close her mouth. Eyes are OK, and had to have several stiches even between her toes which you can't see. Her boyfriend pitbull was smarter and only got a few quills.
I cant vouche for wether this is true or not, but seems beleivable.
