We pick up our pup in August and have just met mum and two dogs from her previous litter (same stud). We haven’t met the stud but his owner has a Fb page for people with his pups to stay in touch. Honestly, the mum and her 2 older dogs are just amazing but I’m trying to work out how much of it is really good training and how much is the calm and affectionate nature. No barking, no jumping up just curious and loving despite never meeting us before. Obviously pup will need training but how much does temperament of mum play a part?
