There has been a lot of puppy posts lately, while I agree they are all cute and lovable (who doesn't love a puppy?) let's remember there are 4 MILLION (that's 4,000,000) unwanted dogs and cats killed every year because they can't find homes. Even if you KNOW you have good homes lined up for your litter, that means someone else's dog or cat will likely be put down.
If you really love your furbabies, consider spaying and neutering. JMHO.
