Time-Share Pet

"Penny De Los Santos wanted a dog but traveled too much to care for one full time. So, she opted for the next best thing: a time-share pet.

For two years, Ms. Santos shared a mellow female Husky mix with her neighbors, who took the dog for about one week a month. They split veterinary bills and the cost of vaccinations and heartworm pills. The neighbors called the dog Nika. Ms. Santos preferred the name Monica.

"It's kind of like Monica had two lives with two families," says the 39-year-old photographer in Austin, Texas."
