Great Pyrenees

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.....

Is it only when he is being touched? If so sound more like something may be painful and I would talk to my vet.

I agree with a visit to the vet. It's possible that you may be dealing with an ear infection. Since Pyrs are my "breed", I'm pretty familiar with the personality.

Human aggression in one raised with the family is not the "norm", so (just as with any breed displaying a change in behavior) I'd rule out a physical ailment first.

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.
