Cambridge England

I am looking for house and dog sitting over Christmas this year.
The house is in a cul de sac with off road parking, not far from Addenbrooke's hospital on the south side of Cambridge. Very close to bus services into central Cambridge, close to a park and other nice areas for walking. There is a secure garden. It is cosy and warm. Wifi and smart TV with sky box provided.
My dog is possibly a German shepherd/border collie cross, a rescue from Romania. She needs to be walked on the lead all the time as can be reactive with some other dogs and will also chase cats and squirrels etc at which point will not listen or come back. But she can be free in the garden where she likes to have balls thrown for her to allow a bit more exercise than is possible when always on the lead on walks. She is very affectionate with people, but not nice to other animals! She likes company, walks, treats and cuddles.
No garden care needed in the winter.
