I actually got to visit my breeders home when her pups were 3 weeks got updates every week and put my deposit down at 8 weeks when I felt comfortable with making my decision. The breeder kept me informed and invited me to come to her home several times and I even stopped by once with only a 30'minute notice because I was in her area. Since she is letting you come by to see the pup after his first shots I dont see the harm in going but if she's not willing to offer a health guarantee for at least a year I'd run as fast as my heels would let me lol. If you don't feel comfortable providing the breeders name (understandably) just p.m. someone if you want their opinion on her
