My parents did recently move to Europe. However, from the time we brought our EM home (at weeks) until about 3 months of each, they saw him daily and interacted with him (play time, walks etc.). His temperament is great, has never shown the slightest sign of aggression, and is also good with strangers when we are in public. However, he has shown some signs of protective behavior in home when we had guests he didn‘t know or contractors performing work. It was shown through barking, but we kept him in a separate room. In a few weeks from now, my parents are going to visit us for about two weeks. They are going to stay in our guest room. About 3 months have passed since the day the saw our dog. I‘m personally not expecting any issues, but wanted to check with you experts. Would recommend a slow introduction? I assume he still remebers them very well, but I‘m really not sure. Again, no issues expected, but I want this to be a nice visit for everyone. Thanks.
