I just got Sadie and she is only 12 weeks so I can't tell with her yet...but Chewy is a year and a half... and he is a lover also. But if he is sleeping and you try to move him he shows teeth and does this low growl!!! What a crank pot! He is a real people lover but he can be moody also... He also only comes when he wants. if you call him and insist he come, he takes his time!!! Sometimes he will take little detours just to show you he is still some what in charge!
