14 month old female sprollie x springer for sale 150 pound please read carefully in Exeter, Devon for sale

Hi I have a sprollie cross springer for sale 150 pound 14 months old female black and white micro chipped spayed dew claw removed very affectionate. Does not like cats at all or skatebored scooters and bikes. I have been working with a trainer for this problem and she tries to chase and nip. I currently use a long line but has impoved with bikes alot. She appears to be quite scared of the dark as she seems more reactive at this point. With proper training she is a lovely dog and intelligent she learns quick. She is friendly and playful with all dogs but has snarled at 2 young lab puppies. She needs alot of daily exersice and mental stimulation. Whenever off she would go for 3 or 4 hour walks per day. She is ideally auited to someone that is very active and an outdoor person. Someone that can give her alot of time as she does not do well being left at home alone for ling periods of time. Definately not with cats she has lived with another female dog but they have had 3 fights maybe a male dog would be better. She sometimes likes to be the dominent one but again with training will be fine. She hasnt lived with kids befour but she would take my neice and nephews dummy out of their mouth so maybe living with no children or older children will be best. I would live for her to have a happy forever home I would hate for her to end up in a shelter so please rwad this thoroughly as she is a huge part of my life. I have to let her go for the better of her with my changed circumstances and I just want her to be happy ps. She looks a little different at the moment as she has recently had her hair cut thankyou
