Bessie is only a year and half old and is already very large for her age, perhaps a fact due to her owners feeding her greatly. Bessie is a Milker dog, meaning that her breed is known for having the largest breasts out of all dogs, but despite this is very active.
Bessie was born blind, and was the runt of the litter of her mother. She was adopted by a university student named Jackie, a female Dalmatian that always loved to have a dog. When she found out about Bessie, she couldn't help but feel pity on her and adopted her straight away.
Over the next year, Bessie and Jackie became best friends. It was a rocky start, especially as Bessie was not potty trained. Fortunately for Jackie though, Bessie hasn't gotten pregnant so her breasts aren't lactating at the moment. Eventually, things began to work and Bessie eventually got potty trained.
Recently, Jackie had been noticing some odd behaviours with Bessie. Bessie has been licking her privates more often and Jackie had seen blood in Bessie's urine. Taking her to the Vet revealed that Bessie is now sexually developed, and capable of mating and producing offspring.
Jackie was both relieved and worried. Revealed that it wasn't anything seriously life threatening but worried at what could happen now. Being that Milker humans are known for being very fertile, it was very easy for them to produce about 8 to 9 puppies in a single litter.
She didn't have long to ponder this thought process as she was going to be out of the country on a university trip for her degree in ecology. As she would be out of the country, she asked her sister Marlene to look after Bessie at her human daycare for atleast a month, enough time for some shenanigans to go down at the human daycare.
