I Have A 6 Month Old Puppy. She’s A Mutt, Not Sure What Breeds?

she’s mixed with. My husband thinks she has greyhound in her. We just got her last night and she seemed very docile but two hours ago she lunged at one of my cats and looked like she was going to bite him. Has anybody had any experience with this? Can she be trained not to hurt my two kitties if she has a hunting dogs instincts?

My 9 Month Greyhound Is Crate Trained Want To Get Her Out Of It So That She Can Join A New Dog We Are Getting?

My greyhound is crate-trained in that she goes in there when I am out (once or twice a week) for 3 hours and is clean. She sleeps by my bed during the night – which we are happy with. We are getting a new dog (a 10 month old greyhoundxgerman shepherd lurcher) in 2 weeks for company for her as she has slight seperation anxiety, although she does settle down in her cage usually – although neighbours said they heard howling the other day. Apparantly, the new dog does not require a crate.
Three issues
1. how do I get her out of the crate? – she is a bit chewy.
2. how do I settle the new dog in?
3. how do I ensure that they get on, particularly when left?
Thanks
