I know female dogs are called B, but I don't like it. just my thoughts. Why must we call our fur baby that nasty name.
To be honest I don't think youll get many welcome responses on what price to charge for your puppies. If you search breeding on here I'm sure you will understand why.
Personally I don't agree with what you've done but it's done.. If you want to breed then spay your bitch buy one that conforms to standard, show her and go from there you will get far more respect for it and a lot more personally out of it. You should only breed to better the breed not to make a profit.
You can't prove your dogs pedigree or whether or not they are infact chihuahuas there is a lot of chis (I'm not sure where you are based?) so you are basically looking At cross breeds as there is no proof of their ancestry without kc registration.
Please sell these puppies with spay/neuter contracts so their owners can't contribute to the over population of poorly bred dogs, there are so many in shelters and I know you love your dog and you bred her for whatever reason but please don't allow her progeny to do the same.
