@tanza I agree entirely ! I never minded plump puppies - but they need to achieve correct weight and maintain it through maturity and into old age ! I don't make any distinction between 'show weight' and anything else. A Basenji carrying too much weight is putting unnecessary strain on the organs and it is as harmful to them as to humans, for the same reasons.
I clouded up and rained all over my puppy people who allowed their Basenjis to put on too much weight.
I am still laughing about an incident after I judged in the Czech Republic - after the show I heard one exhibitor tell another 'my dog is not fat ! He is carrying too much weight !' Which is an expression I often use when judging - it conveys the message without offending the handler !
Condition is key - mine run free for miles most days and even my two current oldies are of correct weight and fit as fiddles - they are probably fitter than I am.
