Suddenly reactive 2 yr old
My 2year old yorkiepoo has suddenly become reactive to certain dogs on walks. Of course they are all big dogs (like Shepards). Most of the time he is more submissive, he’s never even humped another dog. I know he’s maturing and personalities change but this is pretty much a 180 turn. He’s definitely more interested in people vs dogs, but he’s super friendly and always wants to say hi to other dogs (I always ask first though).
I’ve had him since he was 12 weeks old, we live in a city so he’s had lots of exposure to other dogs (in fact his first friend was a giant golden retriever) so this new behavior is really shocking - and concerning. Any suggestions for training I should do to curb this now?
