8 years ago my cousin and her then partner somehow acquired a cross breed whippet (possibly whippet x staff). It apparantly hadn't had the best start in life, having been rehomed from a squalid farm.
They gave the dog a settled home for several years but then the poor thing got passed from pillar to post for a while due to relationship breakdown. During this time the dog showed a couple of instances of aggression towards humans (but doesn't seem to be reactive towards cats or dogs).
Things were just starting to settle down again when my cousin had no choice but to move into a rental that doesn't allow pets. I'm not particularly close to my cousin but heard through the grapevine that she is looking to get the dog privately rehomed.
I'm really concerned about where this poor dog could end up (esp as she seems to have staff in her, you hear of people acquiring these as fighting dogs) and would prefer her to be rehomed within the family so after giving careful thought to it with my partner we are going to bring her to stay with us on a trial basis in the hope we can give her a permanent home to see out her days (my partner is particularly fond of her having done some work on my cousin's previous property a few months ago).
We live at quite a distance from my cousin and we don't drive meaning the pooch will have to get used to buses, trains and all that comes with living in a city. That said, we have a very peaceful, quiet home and live on the edge of a large, very dog-friendly common (and close to several other green spaces). No other pets or children so she will have our full attention.
Ordinarily she's a very chilled dog, quite whippety in that she likes her walks/ bursts of energy but is otherwise a couch potato. But do you think I need to worry about the aggression returning given this will be another unsettled period for her?
What can I do to help her feel safe and settled? Any advice or tips would be gratefully recieved.
We have money to spend on her so could think about consulting a behaviourist maybe?
