They are LOVELY dogs- real couch potatoes BUT they do need to be muzzled,(not in the house they are soppy darlings with people) at least until you are sure of them and they do need to be kept away from small fluffy creatures.
Each dog is different but, if you have more than one you have a pack and they will hunt and they can RUN!!
A friend of mine was forever boasting that she had taught her Lurcher not to hunt and she was fine with rabbits etc.
She got out one night, killed a neighbours pet bunnies and was killed herself on the road chasing something- a cat?? who knows.
It is instinct and it is bred in.
But, as house dogs and "going for a walk in the park" dogs they are the BEST.
They need a short walk am and pm, a short burst of activity at least once a day and they are done!!
They will do more if you want therm to, but that is all they actually want.
They will even adapt to life in an apartment.
And learn to bark at strangers.
