Part of me feels adopting ex-breeders encourages the puppy farming industry, however at the end of the day, the individual dogs don't know this and still need a happier life in a proper home. What are your thoughts? Also, rescue centers talk about nervousness and needing lots of patience and sensitivity while they settle into a home, but has anyone rescued an ex-breeder and had lots of aggression? We already have a small young dog and wanted a playmate for him, but don't want it to back fire and end up with a dog who turns aggressive. Especially now as rescues aren't letting you introduce your dog to a new dog on neutral ground before decided if they're a good match..
