The vet's phone rang, just before closing.
"Hey, it's Karl, my grandmother had a stroke or something, anyway I have to go with my folks to be with her, and I'll need to board Rex for at least a week-"
"Two or three-" said a female voice.
"Okay, mother," said Karl, "Better make that three weeks. Okay? Do you think you could start obedience training, while I'm gone?"
"Oh, Karl, I'm so sorry. I hope she's alright. Don't worry about a thing, we'll take care of Rex. I'm sure we can have him well trained before you get back," said the receptionist sincerely.
The female voice could be faintly heard saying, "Come on, Karl, we have to catch our plane. Don't forget your passport."
"Thanks. Gotta go," said Karl.
He hung up.
The receptionist looked at the phone and shook her head. Bruno was so happy earlier today with his new dog. She picked up the phone again, and buzzed the intercom.
"Doctor?"
"What is it?"
"It's Karl. His grandmother is ill, and he is going to visit her. He needs us to board Rex for a few weeks, and wondered if we could start his obedience training?"
"Hm?" said Chad's father thoughtfully. He glanced up from his microscope and over to the caged dogs where Chad -er, Rex slept. "How many weeks?" he asked.
"About 3 weeks, but I suspect it might be longer. Hard to say. I think the grandmother lives outside the US?"
"Fine. Yes, that will be fine," commented Chad's father. Karl would never know, but his vet was going to make some money on the side collecting and selling Rex's sperm. He was a fine specimen, and so fertile. He should be studded before being castrated, if that was what Karl decided to do. He paused, and added, "I'll call Thad to discuss Rex's training. You can go home, I know it's past closing time."
"Thank you, doctor. I'll lock the main door. See you tomorrow."
