I'm finding her advertisements to be a bit dodgy? Maybe a too to earn money and not pay tax cos $300 for a dog she got free seemed excessive. She isn't a member of the PIAA which is a bit concerning and her advertisements are literally filled with spelling mistakes, the most basic of words such as buy and purebred (pure bread) are misspelt. From her facebook page i suspect she has several of her own pets that she is "breeding" from then passing them off as rescues. Are her own dogs actually desexed?
Shes asking for others to raise the puppies then she pockets the $300 and sell them off.
There is a reason why rescue organizations are monitored by the RSPCA and councils to stop dog hoarding, animal boarding establishments without council permission pretending to be rescue places, to stop dodgy "breeders" passing their pups off as rescues and to maintain a level of hygeine of the animal cages (I doubt she is clean as her photos often can show the background and her house was filthy, she may not think it was dirty but it really was)
If she honestly wants to become a charity then she needs to get the correct council permissions which is impossible for her zoning, register with the appropriate authorities, build the correct council approved enclosures and contact the tax man.
