Going to answer several questions at once.
re: attached. Folks we would not be good breeders unless we were attached. The difference is that I KNOW that they will have a wonderful home with people who ador them. We spend so much time trying to get into their heads so we can find the right match - to get them what they need - I was/am attached to each and every one of the 11 that were born here. But I don't have to have them all to maintain the attachment. LOL. Heck I still get notes and cards from puppies I placed 15 years ago (they do better at that then my kids) I know that they will have a better life being the one and only or with 1 other dog rather than one of a pack. We have placed them (the podengo breed in general) as puppies and as yearlings and as adults - and they are pretty adaptable. Treats and a lap and a yard to run and they are happy LOL.
re: trainability - I find them quite easily trainable - esp compared to the basenji. Typically they are learning to sit, shake and come in nano-seconds. A lady in the D-FW area of Texas has a medium wire that she got at 9 months and she proclaims them the Border Collies of the Hound Group. They are very eager to please.
re: size - I believe that they will all be Grande here. Although mom is 23 3/4" and 50 lbs and dad is 26 " and 57 lbs - last time they were weighed. So not that big.
