The first thing is I must say is how angry

and appalled I am :(
At 2 years old your bitch is only just reaching maturity and anyone with an ounce of sense would not breed from her until this age. You have said she has had 3 litters already and is going to have more any day now :(
That is what I would class as animal cruelty! :(
Your poor dog must be worn out. It is ok you saying she is a wonderful momma,she has to be if you keep breeding her and forcing puppies on her.
She must not have anymore litters after this one.
Why not have her spayed or your male nuetered. :rolleyes:
It is quite obvious to me that you are definately doing this for money and not to better the breed.
