In my part of the country, pit bull owners are just about the only irresponsible dog owners. So unless dogs are regularly shipped in from the South, Puerto Rico or the Midwest, they are the only dogs available at the local pound.
IMO that’s just a terrible shame. Far better that all surrendered pit bulls get put down and more appropriate dogs are spared in order to be given out to adoptive families in their place.
Last October we went to our local county shelter to check out dogs to adopt. Our shelter has 50 cages for dogs and they were all full with only six dogs that were not Pit Bulls. The next county south of us had about the same ratio.
Our local shelter had a German Sheppard/Hound mix that we adopted and she is one of the sweetest animals we have ever been around.
