Hey..so I have an 8 year old whoās never growled in his lifeā¦we moved last year and had a baby so a lot of changes for himā¦hes not a huge fan of the baby but heās generally pretty good with herā¦lately my wife and I have been laying on couch with the dog and he does a low growl at us if we start to snuggle with himā¦Wel move away and hel give us paw to come back but then will tense up and do a low growl again ..any ideas why this is suddenly happening?
