I am concerned. We have two basenjis. The female, Stella, was a pet store dog who just turned 1 in late November. The male, Buster, we rescued through BRAT back in October. Buster has always had some separation issues, wherein he would try to grab our leg or arm (what ever was closest) to either keep us from leaving or from leaving him behind. We understood why, and have been working with him on that and he has made some improvement. Recently, he was sleeping in our bed (which is normal) and I went to push him over to make room (which has never been a problem), and he growled and bit me (pretty hard I might say). Luckily enough I had a sweatshirt on and he did not break the skin, but he left a large bruise on my arm. I don't want to return him to BRAT, he is usually such a sweetheart! Any suggestions with what to do about this?
