A man had his beloved dog collapse in his living room. Minutes later, he came rushing in to the neighborhood vet's office with the limp body of the dog in his arms. "Help me! I think my dog is very sick!"
The vet ushered the two into an examination room, and had the man put the dog on the table. He carefully inspected the animal from head to tail. Shaking his head sadly, he said, "I'm sorry sir, but I'm afraid your dog is dead."
"No! It can't be! You're wrong! You're wrong!"
"We'll see," said the vet, as he opened to door to the exam room and whistled. In walked a cat who went over to the body, jumped on it, and walked up and down, sniffing at the dog. The cat looked at the vet, meowed once, and left the room. "Sir, I'm sorry. The cat also thinks your dog is dead."
"No! I don't believe it!"
"We'll see," the vet said and whistled twice. Two Labrador retrievers walked into the exam room. One started at the head and the other at the tail, walking toward each other until they met in the middle. Each dog barked once and left the room. "They dogs say that your pet is dead, too."
The man, obviously in emotional anguish, finally had to admit that his beloved dog was indeed dead. "I'm sorry, Doc. It's such a hard thing to accept. What do I owe you?"
"What? that much? You hardly did anything."
The vet explained, "Only $50 of that is for my personal services. The remaining $600 is for the cat scan and lab tests."
