I am curious if the dog from Borealis that you are talking about here was a rescue or if you purchased one after having dealt with rescues before, just want to be clear on how you got the dog that carries this kennel name.
I am glad that you have had a great experience with your breeder but you are not the only one to be allowed to post your experiences with a breeder, and the others that have dogs from them do not have a favorable experience. You don't get to diminish their experiences just because they were different that yours.
As for giving an opinion based on pictures or websites that is every member's here prerogative. There are more than a few on this page with a couple of years experience that are used to looking at sites and seeing things that would be flags to them. Someone asked about this breeder and those with experience gave their reasons why they would not select this kennel, even if it was just they don't like the appearance of these dogs. They are entitle to their opinions and those that have actual experiences with the breeder certainly have more than just a casual opinion based off pictures.
As with ANYTHING, you need to do your research. I get that when a scared pup was being presented, you undertook to help this pup, good and bad. That was the right thing to do, don't you agree? But along with taking that pup came multiple problems and plenty of compassionate hard work to "re-educate" this poor pup. I am sure you considered all that.
What I want to do NOW is ask what you did AFTER you took your pup to the vet for the well puppy check up. Did you get copies of your pups medical records documenting the condition of the dog? Did you BUY this pup with papers? Was there a puppy purchase contract stating a health guarantee for a specific period of time? How did you find this particular breeder? Did you research the bloodlines represented in this breeders kennel? How many times did you speak with this breeder on the telephone before deciding to drive 6 hours? Do you have an IPhone or computer to use in a video chat?
And after all that, if the dog doesn't turn out to be the dog you thought you were getting, figure it out. If I purchased a 4 month old cane corso pup, knowing it would top 100 pounds, I would make very sure that I know all about the dog, its parents, its blood lines and its temperament. I think that I might be tempted to contact other owners of her dogs if possible, talk to her veterinarian about health care. With the liability inherent in owning any large breed dog these days, I would then ask myself if I honestly packed the mental gear needed to properly train a dog like this.
And finally, if you found the conditions abhorrent, who did you report this kennel to? The ASPCA would likely be interested, the local Animal Control office, perhaps even the local police would come an take a look. But if you did nothing, you have simply left this breeder continue unhindered and unexposed to continue her questionable practices.
I hope that helps somehow. You cannot/should not rush headlong into a purchase of an animal without doing your proper research before hand. And if what you were told does not match what you yourself actually SEE, that should tell you something.
