I don't know if anyone has read this, but I saw it on Maltesetalk and it is just the most moving thing I have ever read, just heartbreaking. If this has been posted before I'm sure there are still some people who haven't seen this and it is well worth reading. Spay and neuter your pets, leave the breeding to those who know best, and only buy from reputable breeders.
