The number of animals that need homes that are at the Washington County Animal Shelter increased in the past week, because none were adopted and more were brought in.  There are now 14 dogs, as 5 came in, including a Collie mix pup and a young Boxer mix.   There was 1 cat at the shelter, but now there are 6 this week.  Dog adoption fee is $30, which includes an A.V.I.D. Identification Chip.  In addition, new owners will receive a certificate for $50 off spaying or neutering.  Pictures are available online at www.petfinder.com and type in 62263 at the first space in the upper left.  The shelter accepts aluminum cans for recycling to help pay for expenses of housing the cats and dogs.  It is located at 17,990 Richview Road in Nashville.  For more information, call 327-4800, extension 355.
