We've never owned a dog before. Just moved to the Sussex countryside, lots of great walks about and as a family we're quite active, walking and running a lot. We have kids ages 6 and 10 and 2 cats. We'd like to get a dog. I wfh so there's almost always some one at home. We don't want a big dog and had been thinking of a whippet but I've been told sighthounds are a no for cats. Can anyone with doggy experience help suggest good breeds for a first time dog owner in the above scenario. Thank you so much.
