Hi everyone, I adopted a new greyhound two days ago and he has been amazing! The only thing I have noticed is that he tends to bark and howl when I am not around him. Once I let him inside and on a bed in my study with me he calms down. He likes to be on his own and doesn't have separation anxiety but has started barking frequently when left outside alone. Is he just quite anxious and still getting used to the new environment? How do you guys cope with the barking and howling? Thanks!
