So our guy is 18 months and has shown 0 signs of aggression since we had him, not even a growl, at the park all he wants to do is play and have a good time, he loves the rough play but has never come close to showing signs of aggression with other dogs.

We took him to the park yesterday however and there was a new dog there that was rough playing with him, I actually stepped in at one stage because ours was yelping to try to tell the dog to back off and in the end, the dog pushed mine and he fell into the mud and got wet which resulted in him snapping and getting really angry, showing full teeth and moving in a completely different way (he didn't attack or hurt the dog he was basically telling it to piss off). Anyway someone told me that basenji's get aggressive at 2 years old so I'm paranoid now that maybe mine is starting to change, although I know the dog was really aggravating him and he hates getting wet or muddy (as I'm sure most basenji owners can appreciate).

Should I be concerned? Is it true that Basenjis start showing signs of aggression around the age of 2? Any similar stories or advice would be grately appreciated.

Thank you!
