“If you can feel you can cope with it I would look at a behaviourist with Romanian/street dog experience but if he was mine, I would PTS.”
Most rescues have a clause saying you can’t do that without consulting them, you’re supposed to return them...
Also, it’s a very young dog that in the right place may well end up fine.
Mine is coming along nicely - but, I live rurally, don’t have a huge amount of visitors and my children are adults... I was always aware he may well have a fair bit of livestock guardian and/or street dog in there and may well show guarding traits because of that. I didn’t expect it to extend to household members, lol, but he’s done really well with that now.
“Do you know roughly what kind of mix he is - only reason I ask is that a lot of Romanian rescues tend to have livestock guardian shepherd dogs in them to some extent - they can be hypervigilant and wary of people not in their immediate household”
Mine was described in a U.K. rescue as possibly a retriever cross
I didn’t ever think that was likely, but I know his litter mates who were rehomed younger than him have had similar issues as he has and it’s taken their owners a bit by surprise.
“I would definitely muzzle train him. There are some good videos on YouTube of how to do this.”
Muzzle training is a good idea for any dog, but it can be slow going - for reference, I muzzle trained my Rottweiler in less than a week, this dog I’ve been doing it for about 3 months so far, I’m having to work on him not being collar shy first, again, really common with Romanian dogs due to how their handled over there. He’ll stick his nose in no problem, fastening it is still scary.
