Research has proven time and time again that spayed and neutered dogs
have fewer medical problems as they get older. Females dogs that have
not been spayed are at an increased risk for mammary cancer and
infected uteruses. Intact males are more likely to develop prostate
and testicular cancers. All are expensive to treat!
Would you rather pay for a routine or a complicated surgery if it
meant saving the life of your dog? Trust me on this one-it's a total
no brainier. You'll thank yourself later.
Taking care of a litter of puppies is also NOT CHEAP.
