12 month old German Shepherd

Reluctantly selling my 12 month German Shepherd she is a brilliant dog but due to my constant battle with ill health i need to rehome her she is alot for me with being on my own with 3 children and my health and I haven't got the garden space what she needs when ime unable to walk her. All I got with her when I purchased her is her vaccination card and chip number the chip has been transferred into my name so she is registered to me. She is an energetic dog she loves walks getting out and about when my body let's me as i suffer with kidney problems. she is a caring/loving dog she is a strong girl can pull like a train on lead walking but she comes off her lead on the night walk up the fields she gets along with some dogs mainly large dogs she isn't too keen on small dogs or cats she is great around my 3 kids they will be sad to see her go I want her to go to a loving caring home that can give her what's needed she isn't spayed she's half way through heat at the minute this is her 2nd season I am unsure if she is kc registered
