Female MIN-PIN in Richmond, Virginia

I have a 1 1/2 year old full breed female Min- Pin, I got her on 7/ 11/16. Weighs 10lbs, her tail is not docked, and she is not spayed. UTD on her shots including bordatella & rabies a/o 7/18/16 .(next shots due 7/18/xxxx), and she is on heart worm and flea and tick medication which I will give the remainder to you. She seems friendly enough but barks at 1st meeting but warms up quickly, playful, but moderately active. I re-homed her 2 weeks ago but I have another dog and they seem to have severe issues at times like eating and toys, which is a serious problem, and also I had a total knee replacement so I cannot run after her to catch her before she goes to the bathroom in the house.(I was told she was housebroken so I didn't think that would have been an issue but in this case I was misinformed). She goes outside but also inside if I can't catch her in time. I have enrolled her at Petco for dog training which I will have transferred to the person that re-homes her. She has had 1 class 5 left. The adoption fee is the same amount I' m asking for that I paid for her but I AM NOT asking for the amount I paid for her shots , her medications for heart-worm and ticks, Bordatella and rabies and training classes which I have put out already. She has had a litter of puppies per my vet so if I was too keep her I would spade her and which also I was not told and took no notice when I took her. She does not require a lot of attention, pretty low key except with my other dog where she is a terror but she bonds very quickly with humans. I have no idea on her disposition with children of any age. Serious inquires only please. Thanks !
