You received great advice.
That's the good thing about YT, we all have a range of experience with our pups.
Mine was $1400 but from a BYB/puppymill in AR and was about 5 weeks when he was taken from his momma. Needless to say, he had a lot of health/social issues, and it took a long of time, patience, and money for us to get Gizmo where he is to say. All honeymoon money that as saved went towards Gizmo's health bills.
Please remember though, prices does not determine personality or health problems. There are those on here that bought their dogs from a puppy mill and spent $450 at Petland and swear up and down that their dog is fine, and there are those who spent $1700 at a breeder and their dog had a LP by the age of 2 or some weird genetic/personality issue.
Despite those random occurrences, please know that the more researched and better breeder (YTCA recommended) the higher statistics you'll have for a healthy and happy pup. However,keep in mind that those statistics can come at a price of upwards of $1,000.
Good luck!
