In defense of those puppies your breeder is shipping all over the country - why don't you contact someone who will
make her treat her dogs for their problems ??? No puppy should have to live like that - especially when it's a known problem -

if your first puppy had the same things - it's time to ask for help for those other dogs she's selling. She should be reported ...or at least ...tell someone who can offer you some help
poor babies - that has to be itchy and uncomfortable and some things untreated can cause some serious other ailments -
lots of puppies are scared when we bring them to us ...they're being taken away from life as they know it - and in your case - flying in a loud airplane ?? I can see him being timid just for those reason alone - GOOD Luck !
and if the breeder IS a member here ...I hate to say this... but you need to clean up your breeding program - that is so not fair to the puppies AND their people...I don't know who you are - but it seems to me you could do much more for your puppies ....since
YOU brought them into this world.
