Hi all, I'm in need of some advice if possible. Dodger is fabulous, however over the last few weeks he's developed a habit of growling at other dogs. Not necessarily new dogs, some of the dogs he's growling at he's known since he was a little puppy and sees them regularly. All of them seem to be intact males.
He's very well socialised, so this change in behaviour is frustrating and confusing. At training last night he continued to growl the whole way through the class, on and off, as soon as another dog came near him or started to do a training exercise - no treat would distract him, even liver treats which are normally his favourites! He doesn't do anything other than growl at them, the occasional bark if they're further away, but it's still not good.
I've had suggestions from people, but none of these people have Munsterlanders - so I'm hoping you collectively will be able to guide us.
At home he is perfect, no issues at all. It's also only been the last few weeks that this behaviour has become apparent. He's told off each time he does it, and quickly stops - will then even play with the dog he was growling at!
He's still intact at the moment as we wanted to wait for him to mature as much as possible before getting him neutered, but don't know whether this behaviour is due to his hormones and whether getting him done will help to resolve this or not.
Suggestions that have been offered are that he's being protective, or that he's asserting him position in training as there's lots of new younger dogs, that he spends a lot of time with other dogs and wants more time on his own, it's his hormones.... Not sure whether any, some or all of these are correct.
Any tips, suggestions, help willingly accepted. Thanks in advance.
