Well you should have already begun her vaccines already by 6 weeks of age... If you got her from a kennel or pet shop they should have administered her "first shots" already... However, since you are asking this question, she probably has had none...
She will need, at least, 3 inoculations of a Distemper/Parvo Combo vaccine... Each one of these inoculations should be given every 4 to 6 weeks apart... Please, however, due to her age of 10 weeks, verify this with a veterinarian's office...it cost nothing to call, they will not deny you information as their business is keeping dogs well and alive... Parvo is a deadly virus that attacks the very young of canine viciously and is a grizzly death, so no matter the costs of vaccines, if you truly want to do the best for that canine little girl hurry to get her vaccinated asap...
Now, depending on where you live, even in in Europe, there possibly are organizations that help with such fees for the vaccines and at the max, without said assistance, vaccines run around $15 for Rabies vaccines (ONLY BEGIN WITH THEIR FIRST RABIES VACCINE NO EARLIER THAN AT 4 MONTHS OF AGE, ABSOLUTELY NOT BEFORE AS THEIR IMMATURE SYSTEMS WILL NOT TOLERATE) and each Distemper/Parvo vaccine should amount to max, $20 per vaccine every 4 to 6 weeks equaling $60 for those and totaling $75 not including each veterinarian visit which would cost extra... But do not let that prevent you from getting her the proper vaccine attention she needs to remain healthy...
Again you must do your calling around to get estimates and best prices but do not wait too long as the diseases won't... Some rescue organizations like the ASPCA may direct you to get help with payments... Some animals shelters have low cost vaccine clinics as well and may have microchip clinics available as well... I WOULD NOT, HOWEVER, INTRODUCE A FOREIGN OBJECT LIKE A MICROCHIP INTO AN ANIMAL WHO HAS YET TO HAVE THEIR VACCINES FOR PROTECTION AGAINST INFECTIONS... Microchips are wonderful inventions, but you also must be a protective pet owner and keep your dog in a secure fenced area she cannot dig out of or jump over the fencing... And never walk her unleashed outside of the yard or from inside your house... Always carry a stick with you to assure other dogs keep away from her...don't hit the other dog, just wave it at them to keep strays away from her... We have such a cruel world that many people just dump dogs on roads once the cute puppy stage has ended... NEVER EVER GET ANY DOG UNLESS YOU KNOW YOU ARE IN A LIFETIME (THE DOG'S) COMMITMENT TO THAT CANINE!!!!! On the average a microchip (not including the vet visit runs about $20 per lifetime chip, but will need to be registered once injected into her neck... And there will be a yearly fee also to keep your dog safe to be networked over the country which may be $15 a year for the remainder of her life...
And, I know she is a purebred, so what are your intentions? I do hope you are not planning to breed her... For one, the poor Pit Bull is considered Public Enemy #1 (AND TO BREED THE FEMALE PUP WHEN IT IS OF AGE TO DO SO, AROUND 6 TO 10 MONTHS THEY WILL COME INTO THEIR FIRST HEAT/SEASON, IS OPENING HER UP TO BE AT RISK, IT HAS NOW BEEN DISCOVERED, FOR CERVICAL CANCER WHEN SHE IS OLDER) because of a bad rap given them after cruel people teach some Pits to fight in the Pit Ring (how they got their name, but in actuality they are terriers, Staffordshire Terriers, and, by their real nature are sweet and gentle... Yes, I have two I kept after I rescued them off a side rode where the male was walking with a tie out chain severely tight around his neck; it is illegal to tie out a dog and dangerous as well... It can make them strangle or in hot weather not be able, if the chain is twisted, to reach their water buckets...
So again let me get back to what are you plans for this female red pit? It has been discovered by veterinary science now that it is not why to let a female dog have one litter with the thinking it makes them better family dogs... A female of any kind is born naturally with the maternal instinct so female canines are #1 choice for family dogs without breeding them...definitely overprotective of children, but must be raised with them to be and not allow the human child to antagonize the dog in anyway for that is how dog bites happen, female or male, you keep teasing a dog long enough, it will bite, even a cute little mutt... SO PLEASE AM HOPING YOU DO NOT PLAN ON USING HER FOR PURPOSES OTHER THAN A FAMILY PET...
