9 month old black lab in Sterling, New York

I have a black lab that was born October 1st. My son brought her home Christmas Eve. She's very beautiful and has a lot of energy. She is potty trained. As well as crate trained. I never put her in the crate anymore but she still gets in it on her own from time to time. She's great with kids. She's let's my grandson ride her like a horse. She never growls.. She has never snapped or bit anyone. Also she does not bark. She is flea free. No worms.. she does need shots. Baby has always been an indoor dog... we go out often for walks and so she can stretch her legs... we are in the process of teaching her leash manners. She still tries to pull me from time to time but has gotten much better. She is a very healthy dog... and would be a great addition to a family.. I'm sure you're thinking why get rid of her if she's so great... well here's the thing... 1st off like I said my son brought her home. She was just shy of 3 months and she was skin and bones. She had hair missing from the kids pulling on her where she was before hand. She was covered in fleas and had a terrible case of worms... So how could I tell my son No to take her back.... I'm not heartless.. 2nd I have 6 kids + a grandson and my own two small breed dogs. I live in a trailer.. space is very limited. 3rd I'm really ready to get back to work and don't want to leave my dogs locked in a cage all day long... My dogs are treated like family members not just pets. I would really prefer someone who has had a lab before this way I know that you're fully aware of the energy she has... We're asking 200.00 or best offer. Text or call me at the number I've listed... Thanks Annie
