Hi I have a 4 year old male pyrennees,I have had since he was 7 weeks old,great great dog,love him dearly..But as of recent like last 4 months he has been growling at us,like when you go to give him a hug which he normally loves,just dont understand why or what is causing him to all of the sudden be this way..How do i correct it so it does it get any worse..No he has never offered to bite anyone ever..anyone have any ideas or suggestions,yes he is neutered...other than that he is very calm and loveable and his normal beautiful wonderful self.....
I agree with posts who said physical aliments... Vet check is a yes!
Another thing to point out... The "growling" part does not necessary constitute to "aggression" or show of it.
It could be "play growl", "worried growl" or a "growl to say... I am telling you something very serious".
My pyr do play growls all the time while playing.
Then there is also another instant where "fireworks" is being shot up in the night sky and he was "worried" by it... so to tell me, he would "Bark bark Growl.. bark bark" (repeatedly). And after I calmed him down (There is a trick he likes and works on him) and make a "play bow" stance for him to "see" (human doing playbow = nothing serious), he basically went and got his play jug for me to play with him a bit and totally forgot about the "threat" (fireworks).
So not all growls are the same...
I observed as I spent most 24/7 with my pet Pyr who is my "velcro" dog.
I realize this is very out of date with the original post, but I wanted to reply for others who may view this.
Hugging a dog is a "dominant" gesture, which he may be responding to. If there have been any changes in the home to cause his normal "pack leader" to be seen as in a weakened state, he may believe it is his duty to step up and fill the role. His newfound need to growl may mean that he now sees you as a lower pack member and he is telling you to respect his space.
I highly recommend this site for understanding dog behavior:
