My girlfriends parents dog (whom we both lived with for 2-3 years during/after college) was acting funny on Friday...wasn't eating or drinking and was shaking a lot, so they called the vet and the vet said to give him some asprin and bring him in on Monday if it gets worse. Well it did get worse, this morning he wasn't moving his rear legs but was finally eating...he was eating because he was no longer in pain and had become paralyzed from the 'waist' down. We had to put him down this morning at 5 years old. They said if we would have brought him in on Saturday he would have been fine...damn.
