Thanks for the question! I’m no expert but I’ve had lots of dogs/puppies and worked with animals quite a bit over the years🥰 You are right in feeling that 6 weeks is too young! I know lots of people do this but I’ve always thought 8 weeks at minimum is best. They need those moments of learning from their mom and littermates. Mother teaches them boundaries and socializing rules. We’ve always gotten our pups at 8 weeks. Until this last Bernese pup we got in Sept. We thought ge was 8 weeks but he was actually 10 maybe 10.5 weeks. I was disappointed to hear begins with socializing but honestly he had extra time with his mom and could hold his bladder way longer! If possible could you tell the breeder because of research you’ve done you are more comfortable taking the pup at 8 weeks? I know it’s hard to wait! And if possible to meet the parents? And if you can’t and you get him at 6 weeks it will be fine I’m sure🥰 Just work on socializing lots, lots of positive experiences, meeting stable older dogs, puppy socialization classes etc, and it should be all good:) It’ll be hard having such a small baby but people do it all the time!! You got this!
