as was stated a while back, i will get into that in a second and i am sure others may or may not pound on me for this.
but i got morgan at 9 weeks, she did fine, initially she was to do SAR of wich i started her in training, she was doing both tracking and airscenting.
our cardio in appleton will not touch my pups unless my vet who used to work there, finds something suspicious, even if he cleared them at 10 weeks, in another 2 they still can have a problem crop up,"his opinion was"
that it is misleading to puppy buyers that if they are cleared at such a young age they will never develop a problem (not saying anyone here is saying this either). i trust my vets ear, so far she has not let me down, and also used to work with him, if the circumstances were different, i most likely would do things different. My cardio in appleton prefers we local newf people wait till they are at the very least 10 months before he clears them preferably a year.
i let mine go when they are ready, my last litter was ready at 9-10 weeks, if i feel they need more interaction such as the submission training they get from my adults,interraction from mom etc... i certainly hang on to them longer.
My vet is very good at what she does and i take her advice, some may come down on me for it, but so far she has not let me down, she knows her stuff.
