I have a Basenji mix, and he is brand new to me. He was a stray who just showed up on our street last week. Vet's guess is 2 years old and we do not know his history. He is super sweet and loving, gets along well with my dog, but got very aggressive towards my male roommate when he came home last night. The two had been introduced on two occasions, on the street and in our yard (and got on fine). But this was their first meeting after Joey (Basenji) had come in and had a full day in the house. This morning we coordinated so my roommate could be the one to feed Joey before he left for work, but it was one loud, aggressive, hair-raising ordeal.
He barks non-stop, and very pointedly at my roommate. The hair on his back stands up. And this morning he even made some lunging movements towards my roommates feet/ankles - but did not make contact.
Thoughts on whether this is a settling-in issue, that will go away when he feels safe/secure? Or is this a more long-term issue?
Thanks for your help!
