Our 7 month Daisy was turned from delightful to demon. About 1 month ago she started growling when we woke her up and now it's being becoming more frequent. We had her fixed 1 week ago. Is this a stage? We have a 2 yr old bloodhound also (Meg). One minute Daisy is growling and next she is trying to cuddle-up to Meg. At this point we know to gently wake her up and not get in her face but I miss the sweet angel I had. Any advice?
