i had a german sheppard when i was a kid and she bit a porkypine, didn't have money for a vet so i gave her a beer, oh wait i gave myself a beer, yah thats right, anyhow started pullin and an hour and a half later, i was done.
well long story short, about two weekes later she started havin convulsions about once a day, i thought she was going nuts then on the third week i was petting her head and felt somthing sharp and pulled on it, it was a quill, it went the the roof of her mouth and through her brain then lastly thru her skull!...no bull, she was never the same after that...
