Hi all, we have recently taken on a retired greyhound (4 weeks) and everything has been pretty great until a few days ago. Our neutered boy has started growling at our almost 14 year old daughter.
She has been feeding him, walking him, he curls up on the couch with her but suddenly it all changes. She could come back from the kitchen and he stares at her and then starts growling. He has started to go towards her while he growls and it is pretty unsettling as I can see absolutely no reason for this behaviour. She was on the couch just after feeding him and then left the room to go to the toilet but as she came back down the stairs he approached the door barking and growling.
Any thoughts or suggestions on what could be the cause or potential solutions would be ideal.
