I would reccomend one puppy at a time much easier to train and have the one bond to you first before bringing in a second. I really don't see a big difference between the two sexes, but me personally I prefer male. One couple bought two females (both spayed) off me out of different litters and another bought 2 males (1 still intact and one fixed) different litters. I have 2 of each and they seem to get along great.
Introducing a boston to ur cavies (I assume guinea pigs) I would just watch and observe, maybe introduce through the cage first and teach the boston what gentle means. Tiva and Dozer are great with the ferrets and so is Taz (all 158 pounds of him) but Junior and T-Bone are a little to hyper. When we first got Tiva I use to have a ferret and her and Tiva played together beautifully. When I had my brothers Chinchilla Tiva and Dozer played with him also...My sisters poodle plays with her cavie :) Just depends on your training and how hyper the dog is.
When calling breeders just make sure they have done all the tests and when you go see the puppies they should have proof for you to see. The eye's is a big thing so you definatly want both bitch and dog tested for Juvinile cateracts before they were ever bred from, same with the knee's.
I'm in Canada Saskatchewan and if you check out the Dog annual there are alot of breeders...If you tell me where about u are I can check and see if they have any close by and PM you their names and number. The best way to find a good breeder is to check out there place and ask alot of questions, how often they have showed and won ect, how often they breed from the same bitch ect. I found a lot of breeders very friendly to talk to and offer advice and tell me things I didn't know, those were the ones I looked more into.
Registered Boston's I have found go any where from $1000-$2500 thats for pet price all the way up to breeding rights, some go for even more.
A perfectly marked boston has a nice even blaze between the eye's, full black nose, full white collar, front legs white, back legs white up to the hock. Ears stand up on their own, some will crop but I don't see the need, tails should NEVER be docked...if you click on my name you can see pics of my boston's and they have naturally standing ears. The true color of the boston is brindle/white is what I have, junior is a little more black/white, alot of people prefer the black/white. White heads are a disqualification and these usually go for cheaper or are pts when born depends on the breeder.
Questions are good :)
