Theres alot to be said about this breed, and if someone was intrested..I'd very much point them to this breed. Now, some of the cons that can be listed, well..it doesnt apply to every greyhound..not even some, most or whatever. They are very...indepentant of so call cons..They arent guarddogs, 95% of really arent. "Not easy to train" hmm, neither are humans..but I believe this is totally wrong. "Aggressive to small dogs/pets" yes, some can be, some arent. My grey loves my cat and my cat loves her..so again, this con doesnt apply to the whole breed. "Not good swimmers" now this one, i'm not sure...
