I have been researching the best breed fir our family for months. Having debated at length I think a sighthound would suit us perfectly. Probably w retired greyhound but I also love Lurchers and whippets.
The only thing is our new neighbours have cats. We do have a high fat hedge of about 6 feet tall but the cat still often comes in. Obviously I’m worried that this could be an issue . Most of the dogs I’ve seen are either not cat friendly or not tested.
