Newbie Intro

I am new to this forum and new to the APBT.  I've been an admirer for years but have recently and unexpectedly been thrown into the breed first hand!  The cat rescue group I work with was asked to care for a litter of orphaned pitty pups.  We are the only rescue in the area that is willing to do bottle feeding and we couldn't say no and let them be put down!  The mother was taken from an abusive home where there was also an unaltered male Pit chained up with her.  They were both pure bred as far as we know but any neighborhood male could have come into the yard while the bitch was in heat.  The puppies don't look mixed though and have not shown any signs of having suffered physical abuse.  It appears they were simply left out in the yard to die unnoticed alongside their ill mother.  5 of the puppies in the litter were already dead when they were taken away from the home but 5 survived to be brought to us.  When examined by a vet it turned out the mom had tetanus and despite valiant efforts was too far gone and had to be euthanized. 

I took over fostering the babies when they were 4.5 weeks old.  The puppies are now 7 weeks old and thriving!  The vet said three are blue nosed (still trying to figure out exactly what that means).  The only terms I know are from the boxer world so in those terms I would say one is a flashy fawn with a black mask,  two dark brindle, one flashy, one with only a tiny bit of white, one white with brindle patches, one black and white.  Of course there aren't black boxers!  hehe 

4 of the puppies have homes lined up and waiting lists!  We have carefully screened the homes and consulted a local pit bull rescue group for tips on the screenings.  Rosie, the smallest little girl has had absolutely no one interested in adopting her.  She has also wormed her way into my heart and my husbands.  I can hardly bear the idea of anyone else taking her from me!  But in our current situation it really would be best for her to find a different forever home.  She will stay with me until we find that home though.  The pups will not be going to their new homes until after they have been spayed and neutered.  The vet has ok'd for that to be done sometime after 8 weeks for the 4 biggest ones.  Little Rosie will have to wait until she grows a bit more.  She's not even quite 5 pounds yet. 

So far I'm working on basic training like sit, give etc... and will start basic potty training this coming week.  The pups are used to wearing collars and have started leash training.  I would love any tips or advice specific to the APBT that might help me give these guys the best start possible.  I look forward to finding my way around this site and learning more about this wonderful breed.
