Hi,
I am hoping for some advice please about our dog. She is a 10 yr old Lhasa Apso.
We have been cat sitting for a friend of my father's whose son has sadly died. She has taken in his dog who doesn't like cats so we have been looking after the cat. We have had him a couple of weeks and now she has asked if we would like to keep him.
We would love to but I think we are being selfish. Our Lhasa has started chasing him as soon as he comes downstairs (when we first had him he stayed upstairs for a bit). If the cat is upstairs and the dog comes up they are fine. It seems to be when the cat is moving she automatically wants to chase it.
Any tips for helping this or will we need to ask the owner to rehome the cat? I hate to think of the poor cat being stuck upstairs all the time. 
Thanks in advance
