Hi all,
So today my sister brought her dog round to my house for the very first time (she got him as a pup during lockdown so he hasn’t been round to my house before today meaning that today was the first day my dog met him)
My dog is a 9 y/o cocker spaniel, today he growled at my sister’s dog, showed his teeth and stayed at the other side of the room and anytime her dog walked towards mine, he walked away from him and pretty much avoided him the entire time my sister’s dog was here!
Is this normal? Why would my dog be behaving like this? Is it a territorial thing?
